Managing user accounts
You can move user accounts from one user group to another or from one BlackBerry Enterprise Server to another in the BlackBerry Domain. If you move a user account from one BlackBerry Enterprise Server to another, the destination BlackBerry Enterprise Server sends new service books to the BlackBerry device over the wireless network.If you are moving a user’s mailbox to a different Microsoft Exchange Server and moving the user account to a different BlackBerry Enterprise Server, first move the user’s mailbox to the destination mail server. Do not move the user account until the destination BlackBerry Enterprise Server recognizes the new mailbox location.
If you move a user mailbox or change its display name on the messaging server, the BlackBerry Enterprise Server is designed to update the user account within 15 minutes of when the change occurs. If you move a hidden mailbox that does not appear in the contact list, you must update the user account that is associated with the BlackBerry Enterprise Server manually.
When you delete a user account, you can retain the user account information in the BlackBerry Enterprise Server. You can activate the user account again, or the user can continue to use the BlackBerry device as a BlackBerry Desktop Redirector. When you activate a user account that you retained, the user account will have the same settings it had before you deleted it.
