When you try to send an e-mail message to a disabled account in Microsoft Exchange 2000 Server, you may receive a non-delivery report (NDR) similar to the following message:
Your message did not reach some or all of the intended recipients.
The following recipient(s) could not be reached:
Recipient on Date Time
The message reached the recipient's e-mail system, but delivery was refused. Attempt to resend the message. If it still fails, contact your system administrator.
Server Name #5.2.1
This issue occurs because the disabled account does not have the msExchMasterAccountSid attribute. When an account is disabled, this field must be populated with a Windows NT Security Identifier (SID). At a minimum, the well-known SELF SID must be in the attribute.
To work around this issue, enable the disabled account.
Alternatively, to work around this issue if a small number of mailboxes is involved, generate an msExchMasterAccountSid attribute:
To set the msExchMasterAccountSid attribute for many disabled user accounts, you can use the Collaboration Data Objects for Exchange Management (CDOEXM) interface to modify the mailbox security descriptor. Starting with Exchange 2000 Server Service Pack 2 (SP2), a new interface is exposed in CDOEXM. This interface is named MailboxRights. This exposure lets you programmatically modify the mailbox security descriptor.
