BlackBerry phones can receive e-mail, but cannot send e-mail.
This used to work fine at one time for all 25 users (including domain administrators). I think it may have broke when I was trying to diagnose something with the Exchange servers and someone recommended to install the "Update for daylight saving time changes in 2007 for Exchange 2003 Service Pack 2" and it is suggested that it revoked the "Send As" permission for the BlackBerry Enterprise Server service account.
After reading dozens of threads about people having similar problems, I have gone to several places to either add or make sure that the BESAdmin has "Send As" checked and/or added other rights - both through ADUC and the ESM.
Then again, I may not have gone to all of the places, not given enough rights, given too many rights or perhaps not done the right procedure at all.
We are running BES 4.1, Exchange Server 2003 SP2, Windows 2003 R2 SP2 and all are on dedicated servers.
I am stuck!!
