SYMPTOMS
When you start the Microsoft Exchange Server Internet Mail Service, the following events may appear in the application event log:   Event ID: 4018 Type: Error Source: MSExchangeIMC

Description: Unable to start the Internet Mail Connector service because MAPI could not be initialized.

Event ID: 4116 Type: Error 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 not be delivered. The message that was being processed has been moved to the "BAD" folder. Use the appropriate utilities found in the SUPPORT directory of your Exchange CD to view and manipulate these messages.



CAUSE
A possible cause of these errors is that the Exchange service account lacks the proper access rights to the Winnt\System32 (%System Root%\System32) directory.

The service account must have change rights to this directory to be able to modify the Mapisvc.inf file located in the %SystemRoot%\System32 directory.



WORKAROUND
To work around this problem, give the service account at least change rights to the %SystemRoot%\System32 directory.
