Delivery Status Notification (Failure)‏

I have an older 7250 BB.  Ever since I received an email telling me congrats on setting up my account on 4/19/08 (I've had the same account for over 5 yrs) I cannot email one of my contacts that I was able to for years before this happened. 

 

The reason for the problem:
5.1.0 - Unknown address error 501-"#5.1.3 Invalid character ('!') in username."

 

There, of course, is no Invalid character in the user's name.  Anyone have any suggestions? Only thing different with this specific email address is it has under-scores in it. 

 

Thanks!

Sorry to hear you're having problems.  One thing you can definitely do to try and resolve the issue is log into your BIS account and resend your service books, which resolves most issues.  If you're a BES client(your IT guy takes care of your blackberry or on an Exchange server), have your IT guy do this.

 

Good luck.

Thank you for the rely.  It's just my personal bb so I really have no one to work on it.  I may contact my carrier and see if they have a clue.

I know this sounds crazy but I have seen that before when I sent a text message to someone who's # was temp. suspended. Maybe the email address no longer exists? Just a thought.
