I have an Outlook 2003 client that when you click "Reply to All" it returns the error "The messaging interface has returned an
unknown error. If the problem exists, restart Outlook.".
OS is XP pro
I uninstalled outlook and reinstalled - didn't work
ran repair on outlook install - didn't work
closed and re-opened outlook - didn't work, however if outlook is restarted over and over it will randomly work.
ran livecare online scanner - didn't help
anyone seen this before?
