Don't you know wich tcp port uses MS Exchange to communicate with BES ? (we need to add this to fw rules).
Thanks a lot.
Is your BES not on the same local LAN as your Exchange server?
If not, then why?
Exchange <--> BES communication is via MAPI. You'd want to allow any and all ports defined by the MAPI protocol.
