XADM: Mailbox Manager Mailbox Exclusion Information Stored Using MBX Proxy Address (242212)

SUMMARY

The Microsoft Exchange Server Mailbox Manager allows you to select mailboxes that you want to exclude from automated message deletion. With MBClean, there was a limit to the number of mailboxes that could be excluded. This limitation was caused by the way in which the mailbox exclusion information was being stored. To overcome this limitation, Mailbox Manager stores the exclusion information on the mailbox itself. Mailbox Manager uses a custom proxy address of type MBX and adds this proxy address to each mailbox that is excluded. For example, if you use Mailbox Manager to exclude a mailbox named "Test," a proxy address of type MBX is added to the Test mailbox. When Mailbox Manager processes the mailboxes for cleanup, it ignores the mailboxes that have the proxy address MBX.
