We host email for several small business customers. After a recent Blackberry Enterprise Server (BES) update, I’ve had a lot of trouble with the enterprise activation of new phones. The user enters the correct information on the blackberry, and it comes back with an error to contact the system administrator.
In 3 separate cases last week, with both a storm and a pearl, I had this problem. We are running the LATEST BES OS (v4.7) which was realased in the last few days, and even after I wiped the phones, it would NOT do the enterprise activation. Again it gave me a “contact system administrator” error on the blackberry.
Finally I installed the blackberry messenger software on the clients computer. Just by installing the software and connecting the phone, the enterprise activation worked.
For verizon customers you can get the software here:
