XGEN: Updates to the Exchange Server 5.5 SP3 Mailbox Manager Release Notes

This article contains updates to the release notes for the Microsoft Exchange Server Mailbox Manager program included with Exchange Server 5.5 Service Pack 3.

Services Do Not Failover on Primary Node in Clustered Environment

If Mailbox Manager is running on the primary node in a clustered environment, the Exchange Server services may not failover until the Mailbox Manager service is stopped manually. To work around this problem, manually add Mailbox Manager to the Exchange resource group. To do so:

1.	Install Mailbox Manager on all nodes.
2.	On the primary node, start the Cluster Administrator program, right-click the group that contains the Exchange Server services, point to New, and then click Resource.
3.	Type a name and a description for the resource in the Name and Description boxes, and then click Generic Service in the Resource Type box. Verify that the Exchange group is selected in the Group box, and then click Next.
4.	Select the servers you want in the list of possible owners, and then click Next. To select a server, click it, and then click Add.
5.	Select the following service dependencies in the list of resource dependencies, and then click Next: � Add-ins � Microsoft Exchange Directory � Microsoft Exchange Information Store � Microsoft Exchange Message Transfer Agent � Microsoft Exchange System Attendant � Shared hard disk on which Exchange Server is installed To select a service dependency, click it, and then click Add.
6.	Type msexchangemca in the Service name box, and then click Next.
7.	Click Add, type SYSTEM\CurrentControlSet\Services\MSExchangeMCA in the Root registry key box, and then click OK.
8.	Click Add, type SYSTEM\CurrentControlSet\Services\EventLog\Application\MSExchangeMCA in the Root registry key box, and then click OK.
9.	Click Finish.

Cannot Start Mailbox Manager Service on Remote Server in Different Domain

Mailbox Manager cannot start the Mailbox Manager service on a remote server if the remote server is located in a different domain. If you connect to the remote server using the Exchange Server Administrator program, view the properties for the Mailbox Manager object, click the Schedule tab, and then click Clean Now, the following error message is displayed: This behavior occurs even if a trust relationship has been established between the two domains. To run Mailbox Manager on a remote server that is located in a different domain, you must start the Mailbox Manager service on the remote server manually.

User With View Only Admin Role Can Start Mailbox Manager

If you log on to an Exchange Server computer with a user account that has been assigned the View Only Admin role on the site container, you are able to start Mailbox Manager. If you start the Exchange Server Administrator program, view the properties for the Mailbox Manager object, and then click the Schedule tab, the Clean Now button is available. You are unable to modify any of the configuration settings, but if you click Clean Now, Mailbox Manager runs using the existing settings.

LDAP Must Be Enabled

If the Lightweight Directory Access Protocol (LDAP) is disabled at the site level, you may be unable to select a server on the Server Selection tab in the properties for the Mailbox Manager object. The following message may be displayed at the bottom of the dialog box: To prevent this problem from occurring, enable LDAP at the site level. To do so:

1.	In the left pane of the Microsoft Exchange Administrator program, click the Protocols object under the appropriate site. Note that the Protocols object appears under the Configuration object.
2.	In the right pane, click the LDAP object, and then on the File menu, click Properties.
3.	Click the Enable protocol check box to select it, and then click OK.

Excluded Mailbox List Is Not Reset During Reinstall

When you reinstall the Mailbox Cleanup Agent (MBClean), the list of excluded mailboxes is not reset, even though a message appears during installation indicating that all configurations will be lost.
