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,
