Outlook 2007 BETA and your production Exchange server

Now that Outlook 2007 Beta is publically available…have you considered that your users may have downloaded a copy and decided to connect it your production Exchange server?  Did you know you can easily protect your server from these connections?

The Disable MAPI Clients entry can keep unwanted clients (old or new) from connecting to your Exchange server.  In the case of keeping Outlook 2007 Beta off of your server, your entry for this registry key would be:

12.0.0-

Of course remember, when the production version of Outlook 2007 comes out, you will either need to remove this entry or update it.  I will post again when we know the production version number of Outlook 2007 with an update entry.

Also note, that if you are going to try to lock down other versions using this registry key, NEVER lock out the 6.0.0-6.9999.99 range as this is the version number for server-side Exchange components mapi connections.  And you do not need to restart services…updates to the registry entry are looked for every 15 minutes.  Please check out the details in the KB article linked above if you haven’t used this registry key before.

UPDATE:  I have posted the updated version numbers to block Beta versions but not the Production version here.
