SYMPTOMS

When a Microsoft Commercial Internet System (MCIS) 2.0 POP3 or IMAP4 service accesses a remote mail store that runs out of disk space, the following error may occur when the POP3 or IMAP4 client tries to open the mailbox:
ERR Could not open Inbox for '<user name>'.
You may also see the following errors in the Windows NT event log:
Event ID: 40
Type: Error
Source: POP3SVC
Description:
Virtual Server 1: The inbox <path to user's inbox.idx> is corrupt and should be repaired.
Event ID: 3025
Type: Error
Source: RDR
Description:
A write-behind operation has failed to the remote server <server name>.
The data contains the amount requested to write and the amount actually written.
NOTE: This will only occur in heavy stress situations when the SMTP service is still trying to deliver messages to the full mail store.

CAUSE

The POP3 or IMAP4 service attempts to log on a user to a mail store during a disk full scenario while the SMTP service is delivering mail to the same full disk.

WORKAROUND

To work around this problem, stop the SMTP service to reduce the load on the server hosting the remote mail store. Subsequent POP3 and IMAP logons should be processed successfully.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Internet System version 2.0 Mail.
