Hi, I'm getting the same error message on my Nokia E61. I recently activated it on our BES server at the office. My emails and calander are synching ok. Just can't seem to send emails. I was told by someone that it was because I was a Domain Admin. I tried removing myself as a Domain Admin, and making sure that Bes Admin had the correctly privildges on my account. However, I still can't seem to send emails.

If anyone has any solutions, ideas, or suggestion to try, they would be much appreciated. Thanks!
