Outlook is trying to retrieve data from the Microsoft Exchange Server...

I was reading that it could be a global catalog problem, or a nic card problem.  I've pinged the nic card several times today, no problems.   How big can a global catalog be, before you start seeing performance issues...like this error message?

I don't think its a Global catalog server problem its could that exchange server performance.
Most likely would the disk performance of the exchange databases.Run a perfmon on exchange server to diagnose the problem.

So far the troubleshooting assisting is telling me it won't run on my version of Exchange 5.5 and Server 2000.   I've noticed that there may be performance issues with the disk drives, but it's not enough to explain the error messages.   I'll try the BPA and see what that comes up with.

Yikes. I've been guilty of not correctly reading the quesiton. Ex5.5 - on Win2K?

I think you are going to have to look at perfmon counters as per above post.

Yeah,  I'm hoping the company will allow us to upgrade this year.   We have 8 servers and only one has Win 2003 on it.   I just started here a few weeks ago, there is a great deal of room for improvement.
