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.
