Okay, so we have an Exchange 2003 SP2 box. Before I started as the IT Manager here, the GM got an iPhone and the old ITM set that up. So, one user can send/receive emails on the iPhone. Another manager wants to get his email in his iPhone. So, I set it up, except it won't send mail. It gets the error, "Cannot Send Mail. An Error occured while delivering this message."
When I setup my account in AD, I copied the Admin profile. I was able to setup my iPhone just fine, it sends and receives.
At first, I thought it was some setting in Active Directory. I looked high and low and couldn't find anything that should make a difference. So, I copied the problem users AD account and created a test account. Set that account up on my iPhone and it can send fine.
So, on one end, it seems like its a user issue, since two users can send and one can't. But, I copied the problem user and the new user could send fine. I even kept the new user in the same OU.
I'm stuck!!! I've searched and searched for someone else with this issue with no luck. People have issues sending, but its normally company-wide and the issue is with OWA or something on the Exchange server.
Thanks in advance,
