A hotfix is available to change the way that Exchange Server 2003 SP2 handles a disabled Active Directory user account that is associated with an Exchange Server 2003 mailbox

This article describes a hotfix that you can use to change the way that Microsoft Exchange Server 2003 Service Pack 2 (SP2) handles a disabled Active Directory user account that is associated with a Microsoft Exchange Server 2003 mailbox.

If a disabled user account that is associated with an Exchange Server 2003 SP2 mailbox does not have the Associated External Account user right and the msExchMasterAccountSid property, Exchange Server 2003 cannot perform the following actions:

• Enable a different user to log on to the mailbox
• Enable the mailbox to receive messages
• Include the mailbox in a public folder access control list
• Include the mailbox in a mailbox folder access control list
• Move the mailbox
• Successfully run the mailbox cleanup agent

Additionally, an event ID 9548 message is logged in the Application log when Exchange Server 2003 tries to perform any one of these actions. This issue occurs because the Microsoft Exchange Information Store service contains logic that assumes that every disabled user account that is associated with an Exchange Server 2003 SP2 mailbox has the Associated External Account user right and the msExchMasterAccountSid property.

A hotfix is available to change the logic in the Microsoft Exchange Information Store service. This hotfix causes the Microsoft Exchange Information Store service to operate as if the msExchMasterAccountSid property is set to the SELF SID value. Therefore, the Microsoft Exchange Information Store service uses the objectSid property of the disabled user account. After you apply this hotfix, Exchange Server 2003 can perform the actions in the list that is mentioned earlier in this document even if the disabled user account does not have the msExchMasterAccountSid property.
