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 \\

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:

 Event ID:   4055 Source:    MSExchangeIMC Type:      Error Category:  Internal Processing

Unable to move file \exchsrvr\imcdata\work\ to \exchsrvr\imcdata\in\ due to system error. The system cannot find the path specified.
