Can't access Outlook 2007 Calendar

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

Just some random thoughts.

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?

this sounds more like a connectivity issue with the exchange server, make sure the PC's NIC is enabled and has a static or DHCP IP and can get to the internet and access other network resources internally. next see if outlook is in Offline mode, if it is go up to file> and uncheck Work Offline to see if it re-establishes the connection to the Exchange server. another thing you can try is make sure the user is authenticated to Exchange and is not getting the credentials pop-up box on the screen when accessing outlook.

LL:

Not a network latency issue.  His e-mail is coming through just fine, and the time it took (he has a large mailbox with many subfolders) was normal.  Also, as I mentioned, other users have no problem accessing the calendar over the same network.  

I have tried switching back and forth, shutting down Outlook completely, switched to and from offline mode.  No one else has any difficulties opening their calendars, or any calendars that have been shared (his or others).  Problem is still there when I switch off cached mode.  

Only thing I haven't tried is to delete his MAPI profile...where would I find it to delete and how to recreate?

Thanks

Nothing you have mentioned applies.  Everything, including the e-mail portion of his Outlook mailbox is working just fine.  Web browser has no problems connecting.  Automatically authenticates based on his workstation login.  I have never seen anything like this before.

Thanks

The comments by LL Morrison helped, but were not the complete solution.  I was able to use them in conjunction with my knowledge to solve the problem.
