Outlook 2000 "save as" .MSG is not saving in message format??

[John Hardin]

All:

We're trying to save individual messages from Outlook 2000 SR1 to message
format (standard Internet RFC822 format) files.

For most of last week it was working properly. File -> Save As, change
file type to .MSG, and save the message, and it'd be RFC822-format text.

Now, Outlook saves the message as a Word document.

WTF?

How do I get it to go back to the correct behavior, namely saving the
message as an RFC822-format text file instead of a Word document?

I'm not aware of anything having been changed, and this is happening on
many users' systems. I don't see any configuration option for selecting
what the ".MSG" format is, so I don't think the users have twiddled any
knobs.

Thanks.
