Outlook freezes periodically then resumes (exch 2000) 2

[Southridge]

Hello,
Recently, we upgraded our server from NT4-EXCH 5.5 to 2000SBS. Now, with exchange 2000 in place, we have several users who have complained that outlook freezes on them at what seems to be a set interval (I haven't timed it yet). What happens is they are typing, and then they lose the cursor and mouse pointer, and when outlook resumes, everthing that they typed races across the screen to catch up.

I've tried turning off and changing the automatic send\receive function to see if that would help, as well as disabling the virus software. I've also had task manager open to see if any other processes were taking control momentarialy, to no avail. it's as if some background program is taking control for 30 seconds, and then releasing the pc.

All machines have Office xp with outlook 2002 and a combination of windows 2000 pro and windows xp pro, and are pulling pop mail from an ISP, so they have an exchange client and a pop client installed.

Thank you in advance.

I've seen this happen before and typically it's caused by a specific process placing a heavy load on the exchange server. Some of first things I would consider would be:
1. Anti Virus running in Exchange - you may have already addressed this
2. Database maintenance - do you know when yours is scheduled?
3. Users sending large, large attachments - something on an order of magnitude of 10 MB - particularly if you're running AV
4. mailbox management

If you used exmerge to migrate the mail, or didn't wait for the clients to connect and redirect before taking down the 5.5 server, then it's probably hanging on autoresovle. remove, then add back the contacts from the profile.

Thanks to both Jbud and Xmsre for the replies.
On Jbuds comments, As far as database maintenance, I'm sure it's still set at it's default, and I don't know where to look for it, as i'm not that versed in exchange. I doubt its file attachment size, we only have 7 users, and they rarely send any attachments. my guess would be the database maintenance schedule if I can find it?

Xmsre, we actually set up a new server, and then before switching over we exported each user to a .pst file, and then created the user on the new server, and imported the .pst file to their mailbox on the new server. Could autoresolve still be an issue, and how do I check it?

Thank you both for your time.

That migration path would definitely cause the problem. In the outlook profile, The OAB service points to the PR_ENTRYID of the old mailbox's contact folder. Type part of an alias on the to line and click check names. If it hangs, that's your culprit. Removing and adding back the outlook address book service from the client profile will delete the old entry from the profile and add the new one.

What they don't tell you is that it hangs.
