I have recently setup a brand new install of SBS 2011 and it is working well. Exchange is running as advertised and all users are happy.

Now, there are 2 users who would like to work outside of the office and require email setting up in Outlook. No problem - Exchange over HTTP. However for some reason it's not working.

They can access Outlook Web Access okay, but for some reason Exchange over HTTP / HTTPS isn't working. The error message I receive in Outlook is:

"The name cannot be resolved. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action."

I've tried temporarily turning off the Firewall on both the server and the client but this doesn't help at all. Is there something I'm missing or is there a permission that needs enabling to allow Exchange over HTTP to work??

Many thanks
