Outlook 2000 keeps corrupting accounts

[Tom Salinsky]

I have half a dozen email accounts set up in Outlook 2000 and after a
few hours use they start to corrupt and I get a 0x800ccc0e errors.

The problem can be fixed temporarily by exporting the account to
Outlook Express and re-importing it, or by restarting Outlook, but why
do they keep corrupting in the first place?

System: Windows XP
Client: Outlook 2000
Also running: Cloudmark SpamNet, ZoneAlarm

Cheers
