The user has Outlook 2010 and uses IMAP to access Gmail. The option in
Outlook to save a copy of the message in the sent items folder is turned

If the user composes a message and then adds an attachment and sends it only
1 copy of the message is kept in the sent items folder - which is as it
should be.

But if the user opens a file in Word and then from within Word emails the
file 2 copies of the message are in the sent items folder although only 1 is
received by the recipient.

Has anyone come across a similar problem? Is there a fix?

Thanks for any replies.
