General Troubleshooting for Stuck Messages in Internet Mail Service (197792)

MORE INFORMATION

1. In the Control Panel, double-click Services, and then stop the Internet Mail Service.
2. Locate the exchsrvr\Imcdata directory. You can verify this, by checking the registry under the following key:
   
   HKLM\SYSTEM\CurrentControlSet\Services\MSExchangeIMC\Parameters\RootDir
3. Create a temporary directory named TempIMS under \Imcdata.
4. In the Exchsrvr\Imcdata directory, delete the Queue.dat file.
5. Copy the two directories, Imcdata\IN and Imcdata\OUT, to the TempIMS directory.
6. Delete all the files in the Imcdata\IN and Imcdata\OUT directories.
7. Clear out the MAPI queues in MTS-IN and MTS-OUT in the information store. Otherwise, if there are mailboxes on the Exchange Server computer, you need to use one of the following utilities: Gwclean, Profinst, or Mdbvu32.
   
   If you use Mdbvu32, run the Profinst program to install the MAPI profile to be used by Mdbvu32.

   Note If you cannot clear the MTS-IN queue and the MTS-OUT queue by using the Gwclean, the Profinst, or the Mdbvu32 utilities, update Store.exe to the latest version. For additional information about how to update Store.exe, click the following article number to view the article in the Microsoft Knowledge Base:

   Store.exe converts Internet mail to MDBEF format. The conversion is typically where the problem occurs. After you install the update, restart the computer.
8. After you clear the queues, restart the information store and the Internet Mail Service. If this fails, check the message transfer agent (MTA) queues. Run the mtacheck /V /F filename.txt command. You may want to use the /rd or /rl switches.
9. Replay the messages; stop the Internet Mail Service, delete the Queue.dat file, copy the files from TempIMC\IN and TempIMC\OUT to the corresponding directories under Imcdata\IN and Imcdata\OUT, and then restart the Internet Mail Service.
