Had working Blackberry Handheld on Exchange 2007 server (VOODOO7). Installed new Exchange 2007 Server (MUSTANG) in same AD domain and moved mailbox from VOODOO7 to MUSTANG. Since then, I'm not receiving any e-mails on my Blackberry. Tried moving the BESAdmin mailbox (MAPI profile on BES) to the new server and still no e-mails. Deleted the user in Blackberry Manager and recrested. Set the activation password and set the handheld for Enterprise Activation. I get the ETP.dat file (trigger message) in my Inbox but it's stays there and Enterprise activation eventually times out. Any ideas?
