 Last reviewed: April 15, 1997
Article ID: Q157042

The information in this article applies to:
  • Microsoft Exchange Server, version 4.0

SUMMARY

You might receive the following error message when you attempt to start the Microsoft Exchange Internet Mail Connector (IMC) service using the Services applet in the Control Panel: 

   Error 2140: An internal Windows NT error occurred.
The following event will be logged in the Windows NT Event Viewer: 

   Event ID: 4018
   Source: MSExchangeIMC
   Category: Intialization/Termination

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

MORE INFORMATION

This error will occur if a Microsoft Exchange Private Information Store (IS) does not exist on the Microsoft Exchange Server that the IMC is located on. The IMC requires a Private IS in order to temporarily store inbound SMTP messages until they can be routed to the intended recipient(s).

When the IMC receives a message destined for a user on another Microsoft Exchange Server, it temporarily stores the message in the Private IS. The message is then picked up by the Microsoft Exchange Message Transfer Agent (MTA) and transferred to that user's mailbox on their Microsoft Exchange Server.

RESOLUTION

If no Private IS exists on the Microsoft Exchange Server that the IMC is located on, add one by following these steps:

  1. Start the Microsoft Exchange Administrator program.
2. Open the File menu, click New Other, and click Information Store. 3. Select Private as the Information Store Type. 4. In the Server box, select the name of the Microsoft Exchange Server to 
   which the store will be added.
4. Click OK.
