  • PowerPivot, Stocks Exchange and the Moving Average

    - by AlbertoFerrari
    In this post I want to analyze a data model that perform some basic computations over stocks and uses one of the most commonly needed formula there (and in many other business scenarios): a moving average over a specified period in time. Moving averages can be very easily modeled in PowerPivot, but there is the need for some care and, in this post, I try to provide a solid background on how to compute moving averages. In general, a moving average over period T1..T2 is the average of all the values...(read more)

  • Do two portforward rules translate to "and"?

    - by blsub6
    I just set up an Exchange server to replace my DeskNow mail server. I want to start testing my internet mail exchange of my Exchange server. I can only set the MX records on my DNS up to my one external IP address so I was thinking that I could set up a firewall rule on my internet-facing firewall that port forwarded the smtp packets to two different servers. My question is: If I do that, will that mean that the smtp packets will be forwarded to just the first internal IP on the list? Or does it mean that the packet will be cloned and sent to both IPs?

  • Activesync/OWA Desktop Client

    - by prestomation
    At my company we have Exchange 2k3 with OWA being public, serving up Activesync and webmail. There is no pop3 or imap support from our admins. Outlook 2k3's RPC over HTTP is also disabled Is there a desktop client that can connect to Activesync or OWA? If my ipod touch can connect to activesync, why can't my pc? I'd preferably like a linux daemon that could simply forward emails to my gmail address, but I guess I'll take what I can get. Thanks EDIT: In case it was not clear, our Exchange server is hidden completely behind a firewall, and a second exchange server has only activesync and https ports opened to the world.

  • What are possible reasons why a calendar entry in OWA is at a different time than in Outlook?

    - by Ken Pespisa
    We have two Exchange 2003 servers, our primary server and a front-end server that hosts Outlook Web Access (OWA). When I open my boss' calendar via Outlook 2007 (from my Outlook client as well as hers) I see the event scheduled for 10:30 am. When I open her calendar via Outlook Web Access, the same event is scheduled for 4:30 am. I don't understand Exchange well-enough to imagine how this is possible. If you have any ideas why this could be happening, I greatly appreciate it. I'd also very much appreciate any insight you have to how this could be possible. There must be some cached data on the front-end server that causes the calendar entry to appear at a different time, I suppose. Any insight into how Exchange manages that cache and where I could look for an issue would be very helpful. Thank you!

  • User cannot book a room resource

    - by bakesale
    Im having a problem with a specific user not being able to book a room resource. No error message is generated at all. The user attempts to add the room as a meeting resource and it simply doesnt register with the resources calendar. I have tested the resource with other accounts and other rooms for this user but it is only this room that is having issues for this user. This Exchange server was migrated from 2007 to 2010. All rooms except for the problem room were created back on Exchange 2007. This new room was created with Exchange 2010. Maybe this clue has something to do with the problem? This is a paste of the mailboxes folder permissions [PS] C:\Windows\system32Get-MailboxFolderPermission -identity cbr125:\calendar RunspaceId : 448ab44a-4c2a-4403-b46c-fce1106c0823 FolderName : Calendar User : Default AccessRights : {Author} Identity : Default IsValid : True RunspaceId : 448ab44a-4c2a-4403-b46c-fce1106c0823 FolderName : Calendar User : Anonymous AccessRights : {None} Identity : Anonymous IsValid : True

  • SBS2008 : can't have a mailbox accessible from outside?

    - by Bertrand SCHITS
    We have a SBS2008 server with 9 users using the embeeded Exchange. The MX record points to this server. This works fine. We want 2 remote users to also have a mailbox on this server. The consultant say we can't because SBS don't allow to have remote users for Exchange. He may be right but seems very strange to me. I don't find anything related to that. I don't want to touch this server for political reasons. So I can't to the test. Can anyone confirm if Exchange on SBS2008 can or can't be reach from outside ?

  • Outlook or OWA: How can I convert an e-mail message to a draft?

    - by Beaming Mel-Bin
    There's an option in Thunderbird called Edit as new... which converts a message to a draft. I am looking for something similar in Exchange. Reasoning: We migrated old e-mail of a user from an IMAP server to Exchange. The user had many drafts saved. According to exchange though, the messages are not drafts anymore. My hunch is that, if we find a similar procedure as Thunderbird's Edit as new..., that should do the trick.

  • How do I get folder size with Exchange Web Services 2010 Managed API?

    - by Adam Tuttle
    I'm attempting to use EWS 2010 Managed API to get the total size of a user's mailbox. I haven't found a web service method to get this data, so I figured I would try to calculate it. I found one seemingly-applicable question on another site about finding mailbox sizes with EWS 2007, but either I'm not understanding what it's asking me to do, or that method just doesn't work with EWS 2010. Noodling around in the code insight, I was able to write what I thought was a method that would traverse the folder structure recursively and result in a combined total for all folders inside the Inbox: private int traverseChildFoldersForSize(Folder f) { int folderSizeSum = 0; if (f.ChildFolderCount > 0) { foreach (Folder c in f.FindFolders(new FolderView(10000))) { folderSizeSum += traverseChildFoldersForSize(c); } } folderSizeSum += (int)f.ManagedFolderInformation.FolderSize; return folderSizeSum; } (Assumes there aren't more than 10,000 folders inside a given folder. Figure that's a safe bet...) Unfortunately, this doesn't work. I'm initiating the recursion with this code: Folder root = Folder.Bind(svc, WellKnownFolderName.Inbox); int totalSize = traverseChildFoldersForSize(root); But a Null Pointer Exception is thrown, essentially saying that [folder].ManagedFolderInformation is a null object reference. For clarity, I also attempted to just get the size of the root folder: Console.Write(root.ManagedFolderInformation.FolderSize.ToString()); Which threw the same NPE exception, so I know that it's not just that once you get to a certain depth in the directory tree that ManagedFolderInformation doesn't exist. Any ideas on how to get the total size of the user's mailbox? Am I barking up the wrong tree?

  • Is there a working example of using WebDAV for querying Exchange server for calendar items?

    - by Lasse V. Karlsen
    I have tried to hack together a small test project, but it fails with "400 Bad Request" so I'm pretty sure I have done something very basic wrong, but the examples I've found are all in the form of questions, only showing minor pieces of the puzzle, such as a request XML for public folders or whatnot. Is there a complete example somewhere where I can just put in my username and servername and it would list the calendar items in my calendar? This is for C# 3.0/4.0.

  • Migrate SBS 2008 with Exchange 2007 to new hardware

    - by MikeT505
    Hello, We have run out of hard disk space on our existing Small Business Server 2008 and simply wish to upgrade both of the hard drives (currently raid 1) - without too much hassle. My main concern is how to copy across the embedded version of Microsoft Exchange 2007. Is there a simple way to copy all the data across and upgrade? Or is it best to backup and do a clean install? - The difficulty is that it's the same server, so we can't replicate mailboxes for exchange. Any hints or tips welcomed!?

  • How to automatically make a change to Outlook Microsoft Exchange Proxy Settings

    - by Richard West
    I need to make a change on all computers in our domain. Specifically I need to make a change to the Microsoft Exchange Proxy Settings. Our users have Outlook 2010 installed. These setting can be mannually accessed from: Control Panel - Mail - E-mail Accounts - (Select Account) - Change Account - More Settings - Connection Tab - Exchange Proxy Settings I need to have both the "On fast networks" and "On slow networks" check boxes selected. Obviously the idea of asking my users to go through the process above to make these changes is not ideal. Therefore I looking for advice on how I can automatically push these setting to my user base. I have seached the registry but I have been unable to find the location that this setting is saved. Thanks for any help!

  • help with Outlook Exchange server and curl

    - by stib
    I work on a mac in a building full of PCs, and the IT department here doesn't have IMAP access turned on on the exchange servers. So I miss a lot of meetings because I don't get reminders because I access my mail via Outlook Web access. I had written a script to scrape my Outlook Web Access calendar and turn it into iCal format, so I could get my reminders via thunderbird or iCal.app. It basically downloaded the calendar page via curl, parsed the HTML and reformatted all the appointments as ical. it wasn't elegant, but it worked. Then they changed to outlook 2007, and it doesn't work any more. I have a sketchy knowledge of curl, and almost zero knowledge of how outlook works. Can anyone point me towards a reference for getting calendar info out of an exchange server without using outlook? If I can configure curl to get the HTML I will be happy, but if there's a more elegant way, such as getting the calendar info as XML I'll be delirious.

  • Exchange Server 2010 does not include WebDAV

    - by CNLSH
    This is the 1st time I'm dealing with server. May I know what does it mean by "Exchange Server 2010 does not include WebDAV"? Does this mean that EWS does not use HTTPWebRequest and HTTPWebResponse anymore or does not communicates by using the same ports that HTTP and HTTPS? Is it some setting done at the server side that disable the use of WebDav? When it said does not include WebDAV, what does it actually mean? If i really want to use WebDav in Exchange Server 2010, is it possible? Yes, EWS is way better compared to WebDav but what if I wish to use WebDav.

  • Linux clients for Exchange (email and) calendar

    - by jplindstrom
    At $work, the official email solution is Outlook on Windows, connected to an Exchange server. That's problematic for people with Linux on their desktop machine. The Exchange server supports IMAP, and e-mail works fairly well using the usual suspects, e.g. Thunderbird. It also provides the web mail interface, which is fairly crap unless you use IE. (Any other favorite e-mail clients?) The biggest problem is the Outlook Calendar. I still have found no viable Linux client that can replace it. Any recommendations?

  • SMTP 552 4.3.1 Session size exceeds fixed maximum session size.

    - by JL
    I'm having a frustrating problem with one of our clients who is running an exchange SMTP server. I have an emailing component that is written in .net and I've specifically used Mono DLL's to ensure that the email component sends the ELO and QUIT command for each message it sends. Each mail I send will never exceed 10MB's including attachments, which is lower than the session size value set in the clients exchange configuration. Still the problem persists. Any ideas where to look?
