APPLIES TO

  • Microsoft Exchange Server 2003 Service Pack 2, when used with:
    • Microsoft Exchange Server 2003 Standard Edition
    • Microsoft Exchange Server 2003 Enterprise Edition



SYMPTOMS

You try to move high-volume mailboxes from a server that is running Microsoft Exchange Server 2003 Service Pack 2 (SP2). When you do this, you may experience one or more of the following symptoms:

  • E-mail messages remain in the local delivery queue.
  • Outlook Web Access does not respond.
  • The Simple Mail Transfer Protocol (SMTP) service stops responding.

This problem occurs when the message transfer agent (MTA) service is disabled on the Exchange Server 2003 SP2-based server.

CAUSE

This problem occurs because the Microsoft Exchange Information Store service registers a flush in the transit mail task for each mailbox that you try to move. The flush in the transit mail task uses the MTA. If the MTA is disabled, the flush task takes 150 minutes to time out.

During that time, there are fewer tasks available in the Microsoft Exchange Information Store service. Eventually, this condition might lead to task thread exhaustion. Task thread exhaustion affects other functions, such as the local delivery function.

MORE INFORMATION

When you disable the MTA service on an Exchange 2003 SP2-based server, you might refer to the following article in the Microsoft Knowledge Base:

810489 MTA Stacks service supportability guidelines for Exchange 2000 Server and Exchange Server 2003



In this article, you are instructed to set the "Gateway Out Thread" value to 0 (zero). This is a sign of a disabled MTA. After you apply this hotfix, Exchange Server 2003 recognizes this sign, and does not register the flush in the transit mail task for each mailbox.
