Err. Msg.: The Mapi Spooler Has Shut Down Unexpectedly (163512)
The information in this article applies to:
- Microsoft Windows NT Workstation 4.0
- Microsoft Windows NT Server 4.0
This article was previously published under Q163512 SYMPTOMS
When you use the Windows Messaging client included with Windows NT 4.0
Server or Workstation to send an attached file via Internet email through a
POP3 mail server, you may receive the following error message:
Microsoft Windows Messaging Subsystem:
The MAPI Spooler has shut down unexpectedly. Close all
mail-enabled applications before attempting to log on again.
After shutting down and restarting the Exchange client, you receive the
same message.
CAUSE
This error is caused when you send an attached file that has no extension
on the file name. This causes the MAPI spooler to access violate when it
attempts to send the file over Internet email. This problem does not occur
when you use Exchange servers as your mail server, only when using a
POP3/SMTP mail server.
When the error occurs, the mail message does not leave the Outbox so every
time the client starts, it tries to send the message, causing the MAPI
spooler to access violate again.
RESOLUTION
Once you have encountered this error, the only way to stop it is to install
the fix mentioned below or to delete the mailbox.
STATUS

version 4.0. This problem was corrected in the latest Microsoft Windows NT
4.0 U.S. Service Pack. For information on obtaining the service pack, query
