XADM: Uninstalling the Mailbox Manager Service Does Not Remove the Mailbox for the Mailbox Resources Container (264159)

MORE INFORMATION

The first time that the Mailbox Manager service is started, the Mailbox Manager service creates a mailbox on the server that is called "Microsoft Exchange Server Mailbox Manager for server_name."

If you simply uninstall the Mailbox Manager service, you do not remove this mailbox from the Mailbox Resources container.

If you click the mailbox, you receive the following error message: To remove this mailbox, you need to use the Exchange Server Administrator program in raw mode.

WARNING: If you use the raw mode of the Exchange Server Administrator program (admin /r) incorrectly, serious problems may occur that may require you to reinstall Microsoft Windows NT Server, Microsoft Exchange Server, or both. Microsoft cannot guarantee that problems that result from using raw mode incorrectly can be solved. Use raw mode at your own risk.

To remove the mailbox:

1. Start the Exchange Server Administrator program in raw mode by typing the following at a command prompt:

   c:\exchsrvr\bin\admin /r

2. Connect to the server that the mailbox that you want to remove is located on.
3. Locate the Mailbox Resources container in which the mailbox you want to delete is located. The Mailbox Resources container has a parent container that is called the Private Information Store container. Click the Private Information Store container, and then click Raw Properties on the File menu.
4. Under the object attributes, click Obj-Dist-Name, and then select the entire value under Edit Value. Make sure that you have selected the entire value, and then press CTRL+C to copy that value. The value should look very similar to the following:

   (/o=organization/ou=site/cn=Configuration/cn=Servers/cn=server_name/cn=Microsoft Private MDB)

   Note that only your organization, site, and server_name values should be different. Click Cancel.
5. Click the Add-ins container, click New on the File menu, click Other, and then click Raw Object.
6. Click Mailbox, and then click OK.
7. Click Delivery Mechanism, type 0 in the Edit Value box, and then click Set.
8. Click Directory Name, type MCAserver_name in the Edit Value box, and then click Set (where server_name is the name of your server). For example, if your server is named MICROSOFT1, you would type MCAMICROSOFT1.
9. Under List attributes of type, click NonExisting.
10. Under Object Attributes, click Home-MDB.
11. In the Edit Value box, paste the full distinguished name of the home Messaging Database (MDB) where the mailbox that you want to delete is located (this is the data that you copied in step 4). To paste this full distinguished name in the Edit Value box, press CTRL+V. Click Set.
12. Click Apply, and then click OK.
13. In the Add-Ins container, click the MCAserver_name object, and then press the DELETE key. Click Yes to confirm the deletion.
14. Look in the Mailbox Resources container. The Microsoft Exchange Server Mailbox Manager for server_name mailbox should be gone. You need to update the screen by pressing the F5 key before the mailbox disappears.
