Default Exchange communication question

Please Login to Remove!

Hi all,

I'd like to know how BES communicates with Exchange.

Does BES "poll" Exchange? If it does, how often is this polling?

Or does Exchange send out a notification to BES? How does it do this?

it uses mapi and polls exchange alot. Also exchange send BES info a message is recieved and then BES picks it up.

Think of each BES user 3.7 exchange users, its like some one pressing send recieve evey second 24 7 365.

Exchange is a true client server app, the client (in this case BES) registers itself with the Exchange server for new mail notifications. when a new message arrives in the mailbox the client is notified and the client then retrieves the message.
