Blocking Specific Versions of Outlook

You want to be able to control which versions of Outlook connect to your Exchange servers using MAPI, to prevent users from running older, unpatched versions or from running beta versions. Or you may want to completely disable the use of MAPI.

Here is how to do this via the command line - where you can add it into a script for multiple server deployment.

Reg add HKEY_LOCAL_MACHINE\System\CurrentControlSet \Services\MSExchangeIS\ParametersSystem /t REG_SZ /v "Disable MAPI Clients" /d "-11.5608.5606"
Net stop msexchangeis /y
Net start msexchagneis
