BES Express 5.0.3 server on 2008 r2 VM. Was shut down and moved to different host. During shutdown, I'm told that about 70 MS updates started installing. (Another tech did the work.)
After restart, no internal emails on BBs. Internal emails ok with Exchange/Outlook. External emails ok on BBs. Can email externally from BB to internal as well.
Ensured all automatic services on BESX were started, running with regular besadmin account. Besadmin account has sendas/receiveas rights on AD domain still.
BESX's network connectivity ok. Firewall off. Same tcpip settings.
Other tech also went through and uninstalled whatever MS updates came down.
Restarted again.
Trying to look through logs for now...
Any help/wisdom, do advise. Many thanks.
EDIT: Using Exchange 2010 SP1.
