For Hotmail or IMAP accounts, see
http://insideoe.com/faqs/why.htm#dupes - quoted below:

"That can happen if your Hotmail or IMAP account is the default mail account
and OE is configured to both open directly to the Inbox (which downloads
headers automatically) and check for new messages when starting (which also
downloads headers automatically). To stop the duplicates, simply choose one
option or the other, but not both. Click Tools | Options, then remove the
check mark for When starting, go directly to my 'Inbox' folder OR the check
mark for Send and receive messages at startup. If you already have
duplicates showing, click Tools | Synchronize Account or Synchronize All. "

Hi,
I've done this on 2 computers having trouble. It did not resolve the
issue. Still intermittant times clicking send doesn't close out the
compose window, though the message was sent.

This office was just recently converted to all IMAP accounts from POP
accounts. We're seeing the issue on maybe 7 of 30 PC's. In all my
years of support, I've only seen this twice, and once was on my home
PC. I wish I could remember what resolved the issue, as I no longer
have the problem on my home PC.

Any other ideas?

Duplicate messages being received.

You might have a corrupt Outbox.dbx file.

Try deleting it and then try it.

Close OE, search for Outbox.dbx and delete it.
Open OE, the folder will be recreated.
