SYMPTOMS

If you are limiting logons to the information store (which is described in article Q146764, which is referenced in the "More Information" section of this article) without adding the distinguished name (DN) for the Internet Mail Service (IMS), the IMS does not start and you may receive an error similar to the following:
Could not start the Microsoft Exchange Internet Mail Service service on \\servername
Error 2140: An internal Windows NT error occurred.
In addition, the following events are logged in the Event Viewer Application log:
Event ID: 1023
Source: MSExchangeIS Private
Type: Failure Audit
Category: Logons
Description:
DOMSTW\exchservice was validated as /o=MicrosoftCE/ou=northitaly/cn=Configuration/cn=Connections/cn=Internet Mail Connector (NTSTEFANWI1) but was unable to log on to /o=MicrosoftCE/ou=northitaly/cn=Configuration/cn=Connections/cn=Internet Mail Connector (NTSTEFANWI1)

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

This behavior occurs because the Exchange Server Service Account does not have permission to log on to the information store.

RESOLUTION

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this behavior, add the DN for the IMS to the registry:
  1. Stop the information store service on the Exchange Server computer.
  2. Start Registry Editor (Regedt32.exe).
  3. Locate the following key in the registry:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem
  4. Select the following registry value:
    Value Name: Logon Only As
    Data Type: REG_MULTI_SZ
  5. Add the distinguished name of the IMS.

    For example:
    /o=your_organization_name/ou=your_site_name/cn=Configuration/cn=Connections/cn=Internet Mail Connector (IMS_Server_Name)
  6. Click OK.
  7. Quit Registry Editor.
  8. Restart the information store service and the IMS.
