XFOR: Internet Mail Service Stops with Event Log Error 4116

The information in this article applies to:

Microsoft Exchange Server, version 5.5

SYMPTOMS

The Internet Mail Service stops with an event log error 4116, which states The following:

   Event ID: 4116
   Source:  MSExchangeIMC

   Description: An error was returned from the messaging software the
   Internet Mail Service uses to process messages on the Microsoft Exchange
   Server. It is possible that the piece of mail being processed at the
   time will be returned to the sender as a failed delivery instead of
   being delivered. The message will be moved to the "BAD" folder, if
   possible, and the error is not a temporary error. Otherwise it will be
   retried when the service is restarted. Use the appropriate utilities
   found in the SUPPORT directory of your Exchange CD to view and
   manipulate messages that have been moved to the "BAD" folder.

CAUSE

The Internet Mail Service is trying to process outbound messages and receiving an error. The first line in the data portion of the error includes the following:

   74 00 05 00 0e 00 07 80

The last four numbers indicate the MAPI error that was received and caused the Event 4116. The error is 8007000e, which means out of memory. The Internet Mail Service is programmed to stop if it receives such a memory error.

RESOLUTION

To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For more information, please see the following article in the Microsoft Knowledge Base:

Q191014 : XGEN: How to Obtain the Latest Exchange Server 5.5 Service Pack

The English version of this fix should have the following file attributes or later:

   Component: Internet Mail Service

   File Name      Version
   -------------------------
   Msexcimc.exe   5.5.2417.0

STATUS

Microsoft has confirmed this to be a problem in Exchange Server version 5.5. This problem was first corrected in Exchange Server 5.5 Service Pack 2.

MORE INFORMATION

A memory error in this instance incorrectly reports the error condition. A message in the MTS-OUT folder had a property header that contained more than 21 KB of data. This header, plus the sizes of all the other headers, totaled more than 32 KB. The Exchange memory manager enforces a limit of 32 KB per remote procedure call (RPC). The RPC failed because the message properties totaled more than 32 KB. So the Internet Mail Service was not actually out of memory. To resolve this, the error returned in the condition was changed to a non-critical one, so that the Internet Mail Service would not shut down. In addition, if the Internet Mail Service cannot successfully retrieve all message properties at once, it divides them up and retrieves some in one attempt and the rest in a second attempt.
