Sent Mail Box Error Msg

[Larry]

I receive the following error msg when attempting to view sent emails. "The
messaging interface has returned an
unknown error. If the problem persists restart Outlook."
Of course i restarted Outlook many times with no success. I need to be able
to view my sent email, at this point, i will start bcc myself so i get them.

What version of Outlook do you use? What type of mail account do you have?

have a POP account and a gmail account.

Have you tried running a repair of your PST while Outlook is closed?
