Mailbox Manager may not detect hidden mailboxes. For example, when you start the Microsoft Exchange Server Administrator program, open the properties for Mailbox Manager, click Policies, click Recipients, and then click Excluded Mailboxes, a list of mailboxes are displayed. When you click mailboxes in this list, Mailbox Manager does not process them. However, hidden mailboxes are not displayed in this list.

This issue can occur if Lightweight Directory Access Protocol (LDAP) is disabled.

Mailbox Manager uses LDAP to query the directory to build the list of recipients. If LDAP is disabled, Mailbox Manager cannot resolve hidden mailboxes.
