One of my users got a new blackberry to replace his old one through a different provider. We were forwarding a copy of his company e-mail to his old blackberry via a e-mail contact. We changed the contacts e-mail address to his new e-mail address. When anyone sends e-mail to his company address; they get "Delivery has failed to these recipients or distribution lists:" The recipient is his blackberry account. Even stranger is the fact that he actually does receive the e-mail on his blackberry and he gets the same non-delivery message for any e-mail hi sends from his company account. I have deleted and recreated the mail contact several times. I have also deleted his e-mail address from my Outlook. Any suggestions?
