Communicator 2007 \ Outlook 2007 Integration error
There was a problem connecting to Microsoft Office Outlook. Your Outlook profile is not configured correctly. Contact your system administrator with this information."
I have read several blogs and forums regarding this topic. I have ran the gauntlet of uninstalling Communicator 2007, Outlook 2007, Exchange System Manager 2003, and several hotfixes, but nothing has seemed to fix the issue. Until now. The simple fix was to run FIXMAPI from a command prompt. The file itself is located in the "C:\Windows\System32" directory. I opened a command prompt and ran the FIXMAPI executable. It returns no errors or output stating it ran.
My assumption here is it replaces or removes a lock on the mapi32.dll that is shared among the Office and OCS products.
Once you run it, restart Outlook and Communicator 2007. I now no longer get the Outlook Integration errors.
Fixmapi is described here: http://msdn.microsoft.com/en-us/library/bb927655.aspx and http://support.microsoft.com/kb/228457.
