We are using BES with Zimbra and have 6 blackberries running.
Mail and calendar sync is fine from and to blackberry , but not for one user.
For this client the mail sync is ok, but the calendar sync has stopped suddenly. All users are running outlook 2003 on their desktops, and the sync between their desktops and the zimbra server is ok for all users.

Any hints where to look for the missing calendar sync for the user with the problem?
