Outlook 2k/2k3 crashes

Avast Free Antivirus / Premium Security
1

I’ve looked through the forum and didn’t find a relevant answer.
I’m using Outlook 2k on WinXP and Outlook2k3 on XP (with 4.7 Home with 2K and 4.7 Pro with 2k3)
The outlook/exchange plug-in causes Outlook to crash sometimes unpredictably, but more predictably when I’m opening folders with lots of messages (3500-8000)
I don’t have the MS Desktop Search App -never did- nor have I had any other antivirus programs installed on these machines.

Here’s what the application error log kicks out when Outlook 2K crashes:

I have the oleaut32.dll on my machine, but it doesn’t seem to be a part of this equation since I think the OS has installed it.
Any ideas?

Does it mean that when you disable the Outlook/Exchange plugin, the problem disappears?
The error message doesn’t say anything useful, unfortunatelly.

Yes, this isn’t a problem when the Outlook/Exchange provider is disabled.
One thing I failed to mention is that we’re using a Communigate Pro server, and Communigate has an Outlook MAPI that allows exchange-like functionality between Outlook and the mail server. We’re using the MAPI as well.
