I have a blackberry setup, running the latest version of the software and its on Windows 2003 SBS connected to Exchange 2003 with all the latest updates.
On the unit, blackberry pearl, i get a "Desktop email program unable to submit message" when sending mails, well trying to send them. So i can recieve but cant send.
I have set one up recently on someone elses server and although i had problems, i didnt have an issue like this one.
The servers are both identical and both set up in the same way.
Any ideas :):):):):):)
