 Last reviewed: June 5, 1997
Article ID: Q161711
The information in this article applies to:
  • Microsoft Exchange Server, version 4.0, Service Pack 1, 2 and 3

SYMPTOMS

When a message is sent to a recipient in another site by means of a Site Connector, if the destination server is down, the message may be returned by the System Administrator as undeliverable, with the following error message: 

   The recipient could not be processed due to congestion in the message
   transfer service.

CAUSE

The above symptoms will occur if there is an alternate Site Connector for the message to travel over, but the path from the alternate site to the destination server is also unavailable. The message will be re-routed to the alternate site, and then returned to the sender undeliverable as above.

STATUS

Microsoft has confirmed this to be a problem in Exchange Server 4.0. This problem was corrected in the latest Microsoft Exchange 4.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
