XFOR: IMC Cannot Receive Message with Missing Folder

ID: Q146791

The information in this article applies to:

Microsoft Exchange Server, version 4.0

SYMPTOMS

If you run low on disk space, or if you rename or remove the IN directory while the Exchange Internet Mail Connector (IMC) is running, inbound SMTP mail messages are not accepted and the following error message may appear:

421 Internal Error. Connection Closing.

In addition, if you stop and restart the IMC service in Control Panel Services, the following error message appears and the IMC service stops:

Could not stop the Microsoft Exchange Internet Mail Connector on \\<Server Name>

0008: Not enough storage space is available.

RESOLUTION

To correct this problem, stop and restart the IMC service. The IMC recreates the IN directory upon startup. The default working directory is EXCHSRVR\IMCDATA\IN.

MORE INFORMATION

The Internet Mail Connector must have access to the IN directory while the service is running. If the directory is removed, inbound SMTP calls may be refused. If a call is accepted, the mail will be rejected with the following Event Log error:
