I have 13 blackberry users and none are able to send emails on there Blackberrys after an exchange server upgrade although they can receive emails ok.
Everything seems to be setup with the new exchange server but it still will not let users send messages.
I have called a Blackberry support number and they went through settings and varifed that all looked ok and they asked me to run 'handheldcleanup -u -m' command from Dos and it seems to have run successfully but still cannot send mail.
Not sure if anybody else has had an issue like this but if you have can you let me know how you resolved it.
Thanks in advance.
