Question: Can I deploy BES and BES Express with Exchange 2010? Any tips for doing this if possible?
Background: We have a lot of users with personal BlackBerry's and we would like to allow them to start using their devices for receviing corporate email. We don't need full BES features for these users, just the ability to enforce passwords and remotely wipe. Plus users have never wanted to upgrade their data plans to the more expensive BES plans. So BES Express is a great fit.
We already have an existing BES, for corporate owned BB's. We want to keep this as is allows us to enforce several policies not available on BES Express.
You would have to run the two systems on separate servers and administer them from separate interfaces, but I don't see why this wouldn't work, so long as you don't try and enable an account for BES on both systems.
BES doesn't make any changes to Exchange, it just reads data from Exchange and communicates this to the blackberry devices (maybe a little simplified, but you get the point) so Exchange should happily talk to both servers so long as your credentials and permisisons are setup right.
I believe BES Express only supports two users. How many personal Blackberry's are you going to support? Using BES Express could become cumbersome if you have more than a few users.
