  • Introducing the EWS Managed API!

    - by driveby
    Does the system administrator need to install anything extra to get Managed EWS working for clients on Exchange 2010? At the moment I am getting problems just using AutoDiscover via the Managed API so i'm beginning to think the server has been configured incorrectly. Has any administrator here had any experience with setting up Exchange 2010 to allow access via the Managed API? thanks,

  • Removing the XML Formatter from ASP.NET Web API Applications

    - by Rick Strahl
    ASP.NET Web API's default output format is supposed to be JSON, but when I access my Web APIs using the browser address bar I'm always seeing an XML result instead. When working on AJAX application I like to test many of my AJAX APIs with the browser while working on them. While I can't debug all requests this way, GET requests are easy to test in the browser especially if you have JSON viewing options set up in your various browsers. If I preview a Web API request in most browsers I get an XML response like this: Why is that? Web API checks the HTTP Accept headers of a request to determine what type of output it should return by looking for content typed that it has formatters registered for. This automatic negotiation is one of the great features of Web API because it makes it easy and transparent to request different kinds of output from the server. In the case of browsers it turns out that most send Accept headers that look like this (Chrome in this case): Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Web API inspects the entire list of headers from left to right (plus the quality/priority flag q=) and tries to find a media type that matches its list of supported media types in the list of formatters registered. In this case it matches application/xml to the Xml formatter and so that's what gets returned and displayed. To verify that Web API indeed defaults to JSON output by default you can open the request in Fiddler and pop it into the Request Composer, remove the application/xml header and see that the output returned comes back in JSON instead. An accept header like this: Accept: text/html,application/xhtml+xml,*/*;q=0.9 or leaving the Accept header out altogether should give you a JSON response. Interestingly enough Internet Explorer 9 also displays JSON because it doesn't include an application/xml Accept header: Accept: text/html, application/xhtml+xml, */* which for once actually seems more sensible. Removing the XML Formatter We can't easily change the browser Accept headers (actually you can by delving into the config but it's a bit of a hassle), so can we change the behavior on the server? When working on AJAX applications I tend to not be interested in XML results and I always want to see JSON results at least during development. Web API uses a collection of formatters and you can go through this list and remove the ones you don't want to use - in this case the XmlMediaTypeFormatter. To do this you can work with the HttpConfiguration object and the static GlobalConfiguration object used to configure it: protected void Application_Start(object sender, EventArgs e) { // Action based routing (used for RPC calls) RouteTable.Routes.MapHttpRoute( name: "StockApi", routeTemplate: "stocks/{action}/{symbol}", defaults: new { symbol = RouteParameter.Optional, controller = "StockApi" } ); // WebApi Configuration to hook up formatters and message handlers RegisterApis(GlobalConfiguration.Configuration); } public static void RegisterApis(HttpConfiguration config) { // remove default Xml handler var matches = config.Formatters .Where(f = f.SupportedMediaTypes .Where(m = m.MediaType.ToString() == "application/xml" || m.MediaType.ToString() == "text/xml") .Count() 0) .ToList() ; foreach (var match in matches) config.Formatters.Remove(match); } } That LINQ code is quite a mouthful of nested collections, but it does the trick to remove the formatter based on the content type. You can also look for the specific formatter (XmlMediatTypeFormatter) by its type name which is simpler, but it's better to search for the supported types as this will work even if there are other custom formatters added. Once removed, now the browser request results in a JSON response: It's a simple solution to a small debugging task that's made my life easier.

  • Exchange 2003 mail non-delivery (NDR), spam activity? events 7002 & 7004

    - by HighTechGeek
    Windows Server 2003 Small Business Server SP2 Exchange Version 6.5 (Build 7638.2: Service Pack 2) This network has been neglected and has been having email problems for years and was on many blacklists. I was called in after the server eventually crashed... I got the server back up and running, but email problems persist. Outgoing mail delivery is sporadic. Sometimes the mail goes through, sometimes a delayed delivery report is generated after a day or more, and sometimes it seems to go through, but the recipient never receives it. Not sure if spammers are successfully using the server as a relay (see event entries below after turning on maximum SMTP logging)... User PCs infected with viruses and server was blacklisted on many sites (I used mxtoolbox.com) I have cleaned all the PCs and changed all passwords (including administrator) I have requested removal from all of the blacklists - most have removed the listing, some take more time. I have setup rDNS pointer records with the ISP (Comcast) - that was one reason for some of the blacklistings. I have tested that it's not an open relay using telnet as described here: www.amset.info/exchange/smtp-openrelay.asp I followed the advise of a Spamhaus & Microsoft article to enable maximum SMTP logging. http://www.spamhaus.org/faq/answers.lasso?section=isp%20spam%20issues#320 which directed me to Microsoft KB article 895853, specifically, the part 2/3 down titled: "If mail relay occurs from an account on an Exchange computer that is not configured as an open relay" . The Application Event Log is filling with this type of activity (Event ID 7002, 7002 & 3018 errors): Event Type: Error Event Source: MSExchangeTransport Event Category: SMTP Protocol Event ID: 7004 Date: 1/18/2011 Time: 7:33:29 AM User: N/A Computer: SERVER Description: This is an SMTP protocol error log for virtual server ID 1, connection #621. The remote host "212.52.84.180", responded to the SMTP command "rcpt" with "550 #5.1.0 Address rejected [email protected] ". The full command sent was "RCPT TO: ".

  • opath syntax to force dynamic distribution group field as numerical comparison? (Exchange 2010)

    - by Matt
    I'm upgrading a (working) query based group (Exchange 2003) to a new and 'improved' dynamic distribution group (2010). For better or worse, our company decided to store everyone's employee ID in the pager field, so it's easy to manipulate via ADUC. That employee number has significance, as all employees are in a certain range, and all contractors are in a very different range. Basically, the new opath syntax appears to be using string compare on my pager field, even though it's a number. Let's say my employee ID is 3004, well, it's "less than" 4 from a string check POV. Set-DynamicDistributionGroup -Identity "my-funky-new-group" -RecipientFilter "(pager -lt 4) -and (pager -like '*') -and (RecipientType -eq 'UserMailbox')" Shows up in EMC with this: ((((((Pager -lt '4') -and (Pager -ne $null))) -and (RecipientType -eq 'UserMailbox'))) -and (-not(Name -like 'SystemMailbox{*')) -and (-not(Name -like 'CAS_{*')) -and (-not(RecipientTypeDetailsValue -eq 'MailboxPlan')) -and (-not(RecipientTypeDetailsValue -eq 'DiscoveryMailbox')) -and (-not(RecipientTypeDetailsValue -eq 'ArbitrationMailbox'))) This group should have max of 3 members right? Nope - I get a ton because of the string compare. I show up, and I'm in the 3000 range. Question: Anyone know a clever way to force this to be an integer check? The read-only LDAP filter on this group looks good, but of course it can't be edited. The LDAP representation (look ma, no quotes on the 4!) - Also interesting it sort of 'fills the' bed with the (pager=4) thing... (&(pager<=4)(!(pager=4))(pager=*)(objectClass=user)(objectCategory=person)(mailNickname=*)(msExchHomeServerName=*)(!(name=SystemMailbox{*))(!(name=CAS_{*))!(msExchRecipientTypeDetails=16777216))(!(msExchRecipientTypeDetails=536870912))(!(msExchRecipientTypeDetails=8388608))) If there is no solution, I suppose my recourse is either finding an unused field that actually will be treated as an integer, or most likely building this list with powershell every morning with my own automation - lame. I know of a few ways to fix this outside of the opath filter (designate "full-time" in another field, etc.), but would rather exchange do the lifting since this is the environment at the moment. Any insight would be great - thanks! Matt

  • Dependency Injection in ASP.NET Web API using Autofac

    - by shiju
    In this post, I will demonstrate how to use Dependency Injection in ASP.NET Web API using Autofac in an ASP.NET MVC 4 app. The new ASP.NET Web API is a great framework for building HTTP services. The Autofac IoC container provides the better integration with ASP.NET Web API for applying dependency injection. The NuGet package Autofac.WebApi provides the  Dependency Injection support for ASP.NET Web API services. Using Autofac in ASP.NET Web API The following command in the Package Manager console will install Autofac.WebApi package into your ASP.NET Web API application. PM > Install-Package Autofac.WebApi The following code block imports the necessary namespaces for using Autofact.WebApi using Autofac; using Autofac.Integration.WebApi; .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } The following code in the Bootstrapper class configures the Autofac. 1: public static class Bootstrapper 2: { 3: public static void Run() 4: { 5: SetAutofacWebAPI(); 6: } 7: private static void SetAutofacWebAPI() 8: { 9: var configuration = GlobalConfiguration.Configuration; 10: var builder = new ContainerBuilder(); 11: // Configure the container 12: builder.ConfigureWebApi(configuration); 13: // Register API controllers using assembly scanning. 14: builder.RegisterApiControllers(Assembly.GetExecutingAssembly()); 15: builder.RegisterType<DefaultCommandBus>().As<ICommandBus>() 16: .InstancePerApiRequest(); 17: builder.RegisterType<UnitOfWork>().As<IUnitOfWork>() 18: .InstancePerApiRequest(); 19: builder.RegisterType<DatabaseFactory>().As<IDatabaseFactory>() 20: .InstancePerApiRequest(); 21: builder.RegisterAssemblyTypes(typeof(CategoryRepository) 22: .Assembly).Where(t => t.Name.EndsWith("Repository")) 23: .AsImplementedInterfaces().InstancePerApiRequest(); 24: var services = Assembly.Load("EFMVC.Domain"); 25: builder.RegisterAssemblyTypes(services) 26: .AsClosedTypesOf(typeof(ICommandHandler<>)) 27: .InstancePerApiRequest(); 28: builder.RegisterAssemblyTypes(services) 29: .AsClosedTypesOf(typeof(IValidationHandler<>)) 30: .InstancePerApiRequest(); 31: var container = builder.Build(); 32: // Set the WebApi dependency resolver. 33: var resolver = new AutofacWebApiDependencyResolver(container); 34: configuration.ServiceResolver.SetResolver(resolver); 35: } 36: } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } The RegisterApiControllers method will scan the given assembly and register the all ApiController classes. This method will look for types that derive from IHttpController with name convention end with “Controller”. The InstancePerApiRequest method specifies the life time of the component for once per API controller invocation. The GlobalConfiguration.Configuration provides a ServiceResolver class which can be use set dependency resolver for ASP.NET Web API. In our example, we are using AutofacWebApiDependencyResolver class provided by Autofac.WebApi to set the dependency resolver. The Run method of Bootstrapper class is calling from Application_Start method of Global.asax.cs. 1: protected void Application_Start() 2: { 3: AreaRegistration.RegisterAllAreas(); 4: RegisterGlobalFilters(GlobalFilters.Filters); 5: RegisterRoutes(RouteTable.Routes); 6: BundleTable.Bundles.RegisterTemplateBundles(); 7: //Call Autofac DI configurations 8: Bootstrapper.Run(); 9: } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Autofac.Mvc4 The Autofac framework’s integration with ASP.NET MVC has updated for ASP.NET MVC 4. The NuGet package Autofac.Mvc4 provides the dependency injection support for ASP.NET MVC 4. There is not any syntax change between Autofac.Mvc3 and Autofac.Mvc4 Source Code I have updated my EFMVC app with Autofac.WebApi for applying dependency injection for it’s ASP.NET Web API services. EFMVC app also updated to Autofac.Mvc4 for it’s ASP.NET MVC 4 web app. The above code sample is taken from the EFMVC app. You can download the source code of EFMVC app from http://efmvc.codeplex.com/

  • Using Android 2.0 with Exchange server behind firewall

    - by Yurik
    Blackberry has an enterprise server that works with MS Exchange, and pushes all updates to the user's blackberry devices. We are considering switching to Android phones, which supposedly support Exchange servers. Will there be a similar program for Android? Are there any configuration changes that have to be done on Exchange server? (Exchange is behind the corp firewall).

  • Attempting to ping RPC endpoint 6001/6004 (Exchange Information Store) on server on Exchange2010

    - by MadBoy
    I have Exchange 2010 in hosting setup like: TMG 2010 as load balancer Exchange 2010 x 2 (CAS,MAILBOX,HUB on each server) AD1, AD2 machines File witness All people currently connect thru OWA or POP3/SMTP and that works fine. The problem is autodiscovery doesn't work and RPC in terms of setting up Outlook doesn't work too. It doesn't work if I am connected with VPN or not. The thing is it used to work. Before reinstall of my machine 2 days ago I was able to get mails successfully thru Outlook that was set up using autodiscovery (but I was getting reports setting up of new clients wasn't working - so not sure why my outlook continued to work). I used https://www.testexchangeconnectivity.com to track it down and basically the message is more or less this: Attempting to ping RPC endpoint 6004 (NSPI Proxy Interface) on server autodiscover.domain.pl. The attempt to ping the endpoint failed. Additional Details The RPC_S_SERVER_UNAVAILABLE error (0x6ba) was thrown by the RPC Runtime process. I tried different solutions like disabling IP v6, followed couple of links and did all they proposed and it's still at the very same point: C:\Users\admin>netstat -a | find "6001" TCP 0.0.0.0:6001 EXCHANGE2:0 LISTENING TCP [::]:6001 EXCHANGE2:0 LISTENING C:\Users\admin>netstat -a | find "6002" C:\Users\admin>netstat -a | find "6003" C:\Users\admin>netstat -a | find "6004" I followed (and few others): http://helewix.com/blog/index.php/Microsoft-Solutions/2011/02/10/exchange-2010-how-to-open-ports-6001-6002-and-6004-on-your-server-for-telnet-to-work-and-rpc-to-be-able-to-connect-2 http://blogs.technet.com/b/exchange/archive/2008/06/20/3405633.aspx http://messagexchange.blogspot.com/2008/12/outlook-anywhere-failing-rpc-end-points.html Although most relate to Exchange 2007 and I have Exchange 2010 but there's not much things I can find on Exchange 2010 for the current problem. After applying all of those solutions error 6004 changed into error 6001 which doesn't bring me to my problems any closer. At this point even thou error was 6001 and 6004 was no more the 6004 port was still closed while 6001 stayed open. Attempting to ping RPC endpoint 6001 (Exchange Information Store) on server autodiscover.domain.pl. The attempt to ping the endpoint failed. Additional Details The RPC_S_SERVER_UNAVAILABLE error (0x6ba) was thrown by the RPC Runtime process. C:\Users\admin>netstat -a | find "6001" TCP 0.0.0.0:6001 EXCHANGE2:0 LISTENING TCP [::]:6001 EXCHANGE2:0 LISTENING C:\Users\admin>netstat -a | find "6002" C:\Users\admin>netstat -a | find "6003" C:\Users\admin>netstat -a | find "6004" So I reverted back to square one. I suspect it's a problem with TMG but really can't be sure. I tried multiple combinations but all fail.

  • Android Calendar API vs Calendar Provider API

An example of the Calendar API is supposedly located here: http://samples.google-api-java-client.googlecode.com/hg/calendar-android-sample/instructions.html, but the author himself suggests using the Calendar Provider API, details about which are here: http://developer.android.com/guide/topics/providers/calendar-provider.html. Can someone explain to me the difference between the two, and which would be better for me to use for a simple calendar app?

  • Authentication on Exchange using EWS managed API

    - by Jacob Proffitt
    I'm having a weird issue with the Exchange Web Services. The operation I'm attempting is pretty simple—pull a user's calendar items for the current week on our internal website. When testing locally, the ews managed API pulls the calendar information just fine. When deployed to the web server (using integrated windows authentication), it chokes. My trace is telling me that access is denied in the Exchange call. Initially, I thought this was a double-hop NTLM permissions issue, but it turns out that the service actually works for some internal users, but not for most. The only thing I can find that the functioning users have in common is that they are blackberry users and I surmise that their exchange permissions are setup differently. Or are their active directory accounts setup differently? I don't know and it's driving me crazy. I surmise that the blackberry app runs some scripts when a user is added to the application, but I'm completely unfamiliar with what may be going on behind the scenes there. So. Is there a way to duplicate the permissions those users enjoy (either AD or Exchange permissions)? And/or how exactly does one fix the double-hop credentials situation?

  • Why is a journal rule in Exchange 2007 causing messages to arrive in the journal account in non-enve

    - by Bocker
    The bulk of the messages in the journal account on Exchange 2k7 arrive in the appropriate format, message body contains header information while actual message body is attached, but a rather large number of messages are arriving in the journal without this format. The to/from pair of these messages does not show the journal as a recipient, so this isn't a case of the journal receiving these as a recipient. They appear to be journaled using the journal rule, but the format is incorrect.

  • Dual Exchange 2010 on different VM + single public IP + multiple domains

    - by Shivan Raptor
    Here is the scenario: I have 2 Exchange Server 2010 on 2 different Virtual Machines, created by and based on Hyper-V. They have IP and domain: 192.168.5.11, domainA.com ; and 192.168.5.12, domainB.com respectively. The problem is, I only have 1 public IP, say 123.123.1.1 . How do I configure the settings so that I can successfully receive emails using both Exchange servers? Given that I cannot use single Exchange server for multiple domains. -- UPDATE -- To clarify, the domainA.com and domainB.com mentioned above are website domains, instead of multiple Active Directory forests. Users of the two Exchange Server shares the same Active Directory. I know that ONE Exchange Server can handle multiple domains, but I would like to separate them into different Virtual Machines, for load balancing and data separation.

  • Unable to remove broken Exchange 2003 installation (SBS 2003)

    - by Austin ''Danger'' Powers
    We have a non-functional Exchange 2003 installation on our SBS 2003 server that I am trying to uninstall. So far we have never used, and will never use, Exchange on this server- all we need is to remove it from the system (as it is installed on a partition which we want to merge with the main data partition to increase network storage capacity). Attempting to remove it using Add/Remove Programs produces the following error: When doing a search in ADUC to see which users still have a mailbox associated with them, it seems to only be the domain administrator account: As the Exchange installation is broken, it is not possible to run either System Manager or Exchange 5.5 Administrator to make mailbox changes. How can I forcibly remove a mailbox (which does not need to be salvaged or backed up), to allow the uninstall of Exchange to proceed? Any ideas would be appreciated!

  • self-issued exchange certificate for dyndns-url

    - by Sam
    I've got an exchange server behind behind a port to address translation firewall. The server is reachable from the internet using a dyndns-url. Now I want to sync windows phones to exchange mailboxes. To achieve this, I need to install the exchange certificate on the windows phone (send it to the phone by mail, double click). So far so good. But, as far as I can see this does only work if the certificate on my exchange server matches the dyndns-url? So I'd like to know: how do I create a self signed certificate for my dyndns-url and install it on exchange?

    - by realitnzsam
    Hi guys, Recently we moved our Exchange 2003 (SP2) database from one drive to another. Now every other day or so we get errors coming up in the event log: Event Type: Error Event Source: MSExchangeSA Event Category: MAPI Session Event ID: 9175 Date: 10/03/2010 Time: 8:06:15 a.m. User: N/A Computer: SERVER Description: The MAPI call 'OpenMsgStore' failed with the following error: The attempt to log on to the Microsoft Exchange Server computer has failed. The MAPI provider failed. Microsoft Exchange Server Information Store ID no: 8004011d-0512-00000000 For more information, click http://www.microsoft.com/contentredirect.asp. Restarting the Exchange Information Store fixes this instantly, but until we do it Outlook won't connect to Exchange and Blackberry emails aren't pushing out.

  • Removing Exchange 2010 and SBS2011 gracefully after migration to Server 2008 Std R2

    - by user145275
    We have recently completed a server replacement for a customer. They had SBS2011 using Exchange 2010. They now have Server 2008 Std R2 and Google Apps email. We have migrated the DHCP, DNS, Filserver and all 5 FSMO roles to the new 2008 R2 server (today). During the grace period for SBS2011 we intend to decomission the old server completely. Previous experience would suggest uninstalling Exchange 2010 then demote SBS2011 then remove from the domain and switch off. Can I simply demote SBS2011 without removing Exchange? Can't really find any walkthroughs on this. My concern is that if we simply turn off SBS2011 the AD is left in a mess with legacy Exchange objects making any potential reintroduction of Exchange difficult in future, plus I want to do it the right way!

  • Implementing Variable Envelope Return Path (VERP) using Exchange

    - by iammichael
    We're looking into implementing Variable Envelope Return Path (VERP) for improved bounce processing for our application. Our current mail infrastructure is MS Exchange 2007 but are in the process of upgrading to 2010. We're also implementing Postini for spam filtering. Exchange doesn't support sub-addressing (see also this question on disposable addresses) -- and VERP is somewhat of a specialized application of sub-addressing. Are there any options for implementing VERP in Exchange without putting another non-Exchange SMTP relay in front of Exchange to pre-process incoming messages? Specifically could a transport rule be created that could match against the target (non-existing) recipient, store that recipient address in a special header added to the message, and redirect the message to a pre-created mailbox? Note: we have developer resources available if custom code could be used somehow.

  • Cannot get Backup Exec to backup Exchange.

    - by Shawn Gradwell
    I have a media server, Windows Server 2008 SP2 running Backup Exec 2010 R2. The SQL and other Windows agents work but I cannot backup the Exchange 2010 server running Windows Server2008 R2. I have the correct license for the Exchange agent - installed on the media server, and I installed Exchange Management tools on the media server. The 'Microsoft Exchange Database Availability Group' option is greyed out and if I select the server under a new backup job I can expand the 'Microsoft Information Store' option and see the mail database name but showing 0Kb. When I try to back it up it gives an error displaying: The job failed with the following error: Backup Exec attempted to back up an Exchange database according to the job settings. The database was not found, however. Update the selection list and run the job again.

  • Single Exchange 2007 server - two AD domains

    - by TheCleaner
    CURRENT: single domain, single Exchange 2007 NEW: two domains, single Exchange 2007 Can this be done? Details: Current setup is a single W2k3 domain with a single Exchange 2007 server. We are merging with another company that currently hosts their email with their ISP via POP3. We'd like to start hosting their email on our Exchange server using their existing domain SMTP addresses. They don't have an AD domain at all at the moment. Recommendations? Can I do this with a trust between the 2 domains? Requirements: They can't have multiple SMTP addresses on both domains...such as I've seen with articles pointing to "hosting multiple domains". I want companyA to have the same account settings they've always had...companyB to have the same SMTP address they've had and not an additional one on the current companyA Exchange domain. They should be able to collaborate (calendar, contacts, GALs) but should still be distinguishable based on which company they "work for". Please help...thanks!
