We have a BES server Version 126.96.36.199. We are having problems with some of our users not being able to send e-mails from their blackberry devices Cingular 8700s. When they do try to send they get a red x. They all worked fine initially until a MS update a couple of weeks ago which stopped all of them from working. Messing around with permissions made it start working again for everyone. It now stopped working again 2 days ago but only for about half of the users. Any help or suggestions would be appreciated.
