Hi, can you have 2 enterprise servers that shares 1 blackberry mailbox? does this require 2 seperate databases or can the 2nd remotely connect to the first one?

Are you wanting two BES's that use one besadmin account with full access rights over the entire mailstore or two enterprise servers sending and receiving e-mail from one mailbox?

Yeah more info is needed for sure but generally speaking a single besadmin account will work. For info, I have two BESs, totally separate but looking at the same Exchange system. They both use the same besadmin account as all they are doing is using it for access to Exchange, which box the request comes from is sorta irelevant.

For the db I think you might be asking a separate question as the besadmin account is an AD account with an Exch mailbox in the Exch db (mailstore), the BES db is a separate DB the BES uses for all its operations. Multiple BESs can use the same DB but they don't have to (mine have a DB each so aren't aware of each other).

Maybe he wants 2 BB HHs accessing the same mail box.

Not going to happen though.

Could be but from the OP I am guessing he is worried about having a single besadmin account being used by multiple BESs but need lots more info. I am pretty sure there are two separate questins in there somewhere .

Use BES for one BIS for the other; or BIS for both.
