I have one user that this problem occurs with.
He can not create a new email and send to certain people. This is the error he is getting:
Sent Using : Desktop (Secure)
Folder: sent Items
Message Status :Transaction Error - Failure At Service
However, other people he can create new emails and send to just fine. This error can be consistently recreated and doesn't matter where. Another thing, he can always reply to anyone without problems, even to the ones he can not create a new email and send to.
Any ideas? We have a Blackberry Server running Blackberry Enterprise Small Business Edition.
