Ok I am stumped, hence the reason for asking this question.
We had issues with our BES, I checked and the ESM wasn't updated to match exchange server. I updated the BES to match.
Then we start getting one of these two errors:
Desktop Program Unable to Submit Message or
Unlisted Message Error
I did research and found this article http://na.blackberry.com/eng/support/software/sendas.jsp
I followed the tree they provide and it resolved our issue, it was the "set send as" tool that fixed the issue.
Now for some reason my blackberry started giving me this error again (unlisted message error). I can receive emails fine, send emails using my hotmail acct. BB works fine except can't send emails from BES acct. I checked the send as permission for me and it was missing so I added it, still same result. I deleted my acct from BES and readded and reactivated, still same result.
Does anybody know of something I'm missing?
