Whenever I open the Win32 client (both 8.0.0 or 8.0.1 [8/26/2009] have exhibited the problem) on my laptop, I get an error message that GroupWise has detected an error and wants to rebuild my mailbox. I fell for this a few times and had to run the repair but the problem persisted. I ran a standalone GWCheck against the caching folder, structural rebuild, and finally deleted the caching folder and let it repopulate from the POA.

After all that I'm still getting the error! Everything looks OK so I'm guessing there's a registry flag that's not being reset. I've poked through the HKLM and HCCU hives but don't see anything super obvious. Any ideas would be appreciated; it's driving me nuts :-)
