A stub object is left behind in the source database for certain users after a move mailbox operation is complete in Exchange 2003 Service Pack 2

After a mailbox is moved in Microsoft Exchange Server 2003 Service Pack 2 (SP2), a stub object is left behind in the source database for certain users. If you start Exchange System Manager (ESM) and then locate the <Mailbox Store> object, you find the mailbox in the destination mailbox store and also in the source mailbox store.
Although the mailbox is moved successfully from the source server to the destination server, this problem occurs because Exchange 2003 cannot delete the folder hierarchy of the mailbox on the source server during or after the Move Mailbox operation.
Note This hotfix does not resolve the stub mailbox issue. It adds additional events in the application logs that indicate that there was a failure during the Move Mailbox operation. For more information, see the "After you apply the hotfix" section.

After you apply the hotfix

After you apply this hotfix, if Exchange 2003 cannot delete the folder hierarchy of the mailbox in the source server during the Move Mailbox operation, the following events are logged:

Event Type: Error Event Source: MSExchangeIS Mailbox Store Event Category: General Event ID: 10001 Description: The folder with folder ID %1 could not be deleted. Additional information: %2. Event Type: Error Event Source: MSExchangeIS Mailbox Store Event Category: General Event ID: 10002 Description: Failed to delete mailbox with error %1.
In this log entry, Event ID 10001 identifies the folder that could not be deleted, and Event ID 10002 identifies the partly deleted mailbox that cannot be removed from the source server. As soon as you determine the partly deleted mailbox, remove the mailbox manually. To do this, use one of the following methods.

WARNING There is a high risk of disconnecting the newly migrated Exchange 2010 mailboxes if these stubs are removed manually or are removed as part of an Exchange 2003 server decommissioning process. To avoid this problem, you must use one of the following methods before you decommission an Exchange 2003 Mailbox server:
  • Move the mailbox back to the original mailbox store.

    Note This operation will fail. However, the stub object will be deleted.

  • Wait for the maintenance operation to run on the database on which the disconnected mailbox is stored. This operation will remove the stub object.

    • If you want, you can speed up this process by setting the deleted mailbox retention period to zero (0) days. Then, schedule the maintenance to run sooner than the default setting of between 02:00 and 06:00 every day.
    • The mailbox retention period should be reverted after the mailbox is removed. For information about how to do this, see the following Microsoft TechNet topic:

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
