Many external clients/people did recieve duplicate mail from my company's
Exchange server. Hundreds of event ID 3038 appear in Application Log. I
cannot find any resolution from Technet. Permission on all subfolders of
/imcdata/ are OK. Virus scan (file level) is disabled. GroupSheild installed
on Exchange and is running. What is the cause and resolution? Any help on
this one would be greatly appreciated.
Event ID 3038:
An attempt to remove processed messages from the outbound store queue has
failed. The removal will be retried later. If the messages are not removed
before the service is shut down, the mail will be resent at service startup
causing duplicate mail.
