I have an Exchange Server 2003 and some users who have Blackberry's. Setting the Blackberry's up is relatively simple, much like setting up a Windows Mobile or Palm phone but the settings only seem to work for at most 3 months. Then it will tell the user to reenter the password, or username, etc. This never works and they have to remove the account and set it up again. This can be quite a hassle, especially for those that it happens to monthly. Does anyone have any idea why this would be occurring?
It only appears to affect the Blackberry's. Thanks!
