I'm having the same issue. I have a brand new 8830. We have a BES running on a server 2003 box with Exchange 2003. The only different thing I did was take a backup with the desktop manager software of the users old blackberry then restored it to his new BB after enterprise activation. (I never have this problem when I don't restore any old info). Old BB was an 8703e, new one is an 8830. Whe he tries to reply or forward a message there is no "send" option, only an option to save the draft. I tried deleting Desktop[CMIME], and resending service books from the server but that didn 't seem to help. Anybody got any ideas?
