We use Oulook 2007 with Exchange Server 2003. I have a user who all of a sudden cannot open his calendar. Both his administrative assistant and myself can open on our computers. When he clicks the calendar icon, he gets the following message:
The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.
This is happening inside the office from a desktop, not a remote connection, so Outlook is always connected when the server is running. We run Outlook in cached mode, and his is connected. He is getting new e-mail (without hitting send/receive), and can access all other aspects of his Exchange account.
I tried deleting the .ost file to see if that would help, but I am still getting the error message. I have not tried repairing Outlook (this has never worked for any problem that I have had in the past, so I rarely give it a try). I also have not tried reinstalling Outlook.
Has anyone run across this, and if so, what did you do to fix it?
Thanks in advance,
Craig
This could suggest network latency issues perhaps?
Can you switch away from the calendar folder then back again to correct the problem?
Switch to offline mode then back to online mode?
Log into the assistants PC as him and set up outlook and try there. Is the problem still evident or is it fine from that PC?
Likewise what happens if the assistant logs on to his machine and tries to open his calendar?
Delete his MAPI profiles and recreate it?
Is the problem still there is you switch of cached mode?
