Outllook 2007 Data File Check

I’ve been working on this problem for some time. I have several end-users who are running Outlook 2003 & 2007 on a Windows SBS 2003 domain (exchange 2003). Almost everytime they open Outlook the program begins a data file integrity check. I experience this myself occasionally (Vista Ultimate/Office 2007) but not with the regulariryof these end-users.

I’ve tried disabling add-in’s, uninstalling google search, uninstalling Microsoft Search, and am about to uninstall Spam Bully Anti-Spam (I’d really rather not).

I’ve spent a few hours on this over the last week or so. It nothing pressing but the DFC is getting on peoples nerves and they on mine.

Has anyone seen this? Has anyone resolved it? If so, how?
