However, when a user connects via terminal services, they cannot open Outlook 2007. They get a message "The action cannot be completed. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action."The Exchange Server 2007 with SP1 has been installed in the Exchange server.Server One is runningWindows 2008 64-Bitand Exchange 2007Server Two is runningWindows 2008 64-Bit with 20-Terminal Server licenses and 20-Microsoft Office Enterprise 2007Please help us to getthe solution in this issue.Thanks in Advance,Manikandan R

Hi,Please verify if the issue occur to all the users.Please check if the connection has been set on the terminal server. Please try to create a new windows profile and outlook profile to check the issue again. Please check if other outlook users(not access outlook from terminal) have the issue. Also please check the event viewer to see if any error event have been logged there. Please post the detail error information here. Besides, please check the article below and try to add the register to see if the issue will disappear.

More information to share with you:The Exchange Server Outlook Anywhere feature does not work correctly if it is installed on a Windows Server 2008-based server that has Terminal Services Gateway installedhttp://support.microsoft.com/Default.aspx?kbid=954034Regards,Xiu

We are running the exact same setup, and I am wondering what you did to resolve this issue? I have tried the 2 below solutions and neither have worked. However we do not have terminal services gateway installed so we did not try that fix. Any info would be great.
