Thanks.

I probably didn't explain it very well in the first post so bear with me.

We currently have 2 Exchange servers. One is the main Exchange server and one is a backup one. They are both in different locations on different subnets. The live one replicates data automatically to the backup one over the network, and the backup Exchange server can take over where the live Exchange server left off if there was ever a problem with the live server.


So... I currently have a BES server which is attached to the live Exchange server, but also would like a backup BES server which will attach to the backup Exchange server.

Is it possible for this to happen with BES Express or does it need the full blown version of BES?

Also, as the BES Express takes all the mailbox settings from AD, will it automatically redirect the mailboxes once the backup Exchange server takes over and handles the mailboxes?
