Fatal Error in outlook 2003

[SheilaC]

I received this error message "a fatal error has occurred in outlook. The
data in your envelope has been lost, but your document is still available.".

This has happened three times today. I lose all my envelope data (to, cc,
bcc, attachment information). I usually can cut and paste the body of the
email.
What can I do to resolve this error besides create a new profile?

THanks for any information.
