To work around this problem:

�

Move the user's additional mailbox to the same mailbox store (you must be an administrator to do so). However, you may not be able to use this method if users have additional mailboxes in different storage groups or stores. -or-

�

If the user wants to keep the mailbox on the same store: 1. Start Microsoft Outlook with the second user profile (for this example, User2). 2. Open the Inbox of the first user profile (for this example, User1). 3. On the View menu, click Current View, click Customize Current View, and then click Group By. 4. In the Expand/collapse defaults list, click All expanded.
