Week 29 Article 05 - Darn Blackberry!! User cannot send/receive emails from device after a few hours!!

Platform:
Blackberry Enterprise Service 4.x
Microsoft Exchange Server 2003
Microsoft Windows Server 2003

Symptoms:
After setting up a user for blackberry access, he/she can send/receive emails from the device fine till after a few hours. After a few hours, when he tries sending emails from the device, a red X is displayed beside the message, and an error message stating that the message was not delivered.

Troubleshooting Steps:
1. Checked permissions ( http://support.microsoft.com/default.aspx?kbid=912918)
2. From 1. above, found that the Blackberry account did not have the Send As permission anymore.
3. Had a look at the user account permissions and found that one of his group memberships was to an account with domain wide administrator access! This is a NO NO as per the KB article
4. Removed user from the group. Gave the Blackberry account Send As permission on the user account.
5. Restarted Microsoft Exchange Information Store, Blackberry Dispatcher and Blackberry Router service.
6. Tested sending of emails from the device.

Moral: RTFM! There is a reason why there is a KB article and set of steps to do things
