I have just migrated mailboxes to a new Exchange 2010 server.

BlackBerry Enterprise Server is not communicating with the new Exchange. I was prompted to enter the usernames & Exchange server name, but BlackBerry is still not communicating with it.

Can someone please assist me on how to troubleshoot this system?

What Exchange server name did you enter? – Shane Madden Jun 1 '12 at 0:05
servername.domain.local – Ash Jun 1 '12 at 0:42
But which server is that? It'll need to be the CAS server. Also, are you running up-to-date BES and the MAPI CDO? – Shane Madden Jun 1 '12 at 0:55
That is the Exchange 2010 server. BES was connecting fine with an Exchange 2007 server. Surely there's a quick settings change within BES to connect it to the Exchange 2010 server? – Ash Jun 2 '12 at 1:38
There are a lot of things that can break a BES connection to the Exchange server when you change Exchange versions. Again, check the BES and MAPI CDO versions. And check whether the BES account has the correct permissions for it to function against the 2010 server. And have you moved the BES service account's mailbox to the 2010 server and updated the MAPI settings when that occurred? – Shane Madden Jun 2 '12 at 17:35

You'll need to upgrade the BES software. 4.1 doesn't work with Exchange 2010; you'll need 5.0.

See the compatibility document for more detail.

Thanks for that. I'll deploy v5 on a different server. – Ash Jun 4 '12 at 5:07
