I recently upgraded our BES 5 to BES 5.1 with the MR1 for the service pack...
after the install, none of the devices are receiving e-mails or syncing calendar anymore - when i try to re-activate my own device, the ETP.dat gets stuck in the Outlook inbox.
I can send PIN messages from the BAS and they will appear, but I cannot send Emails from the BAS, these messages wil only appear in the outlook inbox and not on the device.
All services are running like they should, there have not been any firewall/routing changes in the environment.
Does anyone know what might have happened or what i can do to resolve this?
