BlackBerry:

Question:  I can't send from my BlackBerry even though my PIN number matches within my Client Console Web Page.  Also, these e-mails have made it through my outbox and into my send items folder.

Answer:  We've found sometimes that even though your PIN number matches and your outgoing e-mail gets placed in your sent items folder, your mail may not be sent.  We would have to take a look in the "Response Handler" log for the answer.  If you see an error corresponding to your device sa key that states "relaying denied" please see:

If your key does not appear at all within the Response Handler Log, we've found that deleting the account from the Blackberry and then re-registering the Blackberry will do the trick.  There may have been an error when registering originally that could have caused this.  Just delete the account from the Blackberry, post registration messages by clicking on the "Synchronize Device" button within your client or admin console web page, then register.  Through the OTA loads during registration, you will be able to regain your calendar, contacts and tasks.
