Exchange 2007 SP3 Breaks BES Express (BESX)

Found yesterday after installing Exchange 2007 SP3 on an SBS 2008 box with BESX 5.0.2 nobody was getting emails on their Blackberrys. Checked the services and the BlackBerry Mail Store Service would not start.

Checked the Service Configuration and more importantly the MAPI profile and this generated an error:

MAPI Initialize error 800004005

Checked online and found a couple of articles suggesting to run Fixmapisvc.exe in the tools directory on the installation source. This returne with

MSEMS service information already exists in C:Windowssystem32mapisvc.inf

I checked the file and this was a bit of a red herring on the server as SBS2008 is 64-bit so if you are checking this file is actually located in C:windowsSysWOW64 which is the new System32 folder.

Anyway after clearing out this information from the inf and re-running the fixmapisvc.exe command this did not fix the issue.

Tried reinstalling the Microsoft Messaging API and Collaboration Data Objects 1.2.1 (download)

I also tried creating a new besadmin account as per Blackberry KB04293 this generated the same Initialize error.

Uninstalled the Microsoft Messaging API and Collaboration Data Objects and then reinstalling, and this fixed the issue.
