Outlook 2007 to Exchange 2007 Very Slow Connection after Microsoft Office Update

I have a site that has about 15 computers connected to a Windows 2008 SBS server. Users access email through MS Office 2007 Enterprise. There is a mix of Windows XP and Windows 7 computers.

All was working fine until last nights update of Microsoft Office. Users that applied the update are now having to wait 3 to 10 minutes for Outlook to connect and update folders. Other users are running fine. If you access a users account from a computer that was NOT updated, the mailbox comes up instantly.

We have rebooted both the server and the workstations. I have also turned off the Windows Search service (disabled) and that seems to help a bit, but it still takes about 3 minutes to connect.

Once beyond the initial few minutes, Outlook seems to run fine. That is until it is restarted.

Thanks for your help.

These computers were working yesterday with no problems. Not sure why these 3 computers are having problems now. They get Not Responding when the user clicks on the screen.

Right, the link i posted is very much relevant to this issue you are having, directly from MS.

Worked out the solution. Seems that the Microsoft Office Update that ran last night, somehow corrupted the Mail Profiles for three of my 15 users. 2 are XP and 1 is Windows 7. All experienced extremely slow connections and startup of Outlook.

To fix: Had to go into Control Panel/Mail and removed the existing profile and exited the mail configuration, without any profiles listed. Then when back into Control Panel/Mail and setup a new profile and configured as normal. Cached mode is setup on Windows 7 machine and it works now. The two XP machines are non-cached and work fine as well.

The full solution was to delete and re-add the profile. But this article had good information.
