I have just upgraded from ISA 2000 on SBS 2003 and have found that my Blackberry users can no longer send email from their handheld devices.
All other wireless connectivity operates and they can receive mail to the device but mail will not be sent from the handhelds.
I am sure that this is related to the ISA 2004 upgrade but I have the relevent 3101 TCP ports open in both directions.
Is there anything elses that I shoudl ensure is passing through my firewall?
We are struggling here without the service and our Service provider is lacking in ideas.
Any assistance would be appreciated.
