We have a user who's outlook professional 2013 will not open. Says "Microsoft Outlook has stopped working" etc. and then it closes. After a KB was installed it happened (KB2760539). However further exacerbated the problem by installing newer updates including windows 8.1 in hopes of it fixing the issue. Now we cannot uninstall that KB at all, and I don't even see it. I couldn't find the registry location for it either. I would rather not go back to a last good configuration date because we would like to have the computer updated and we would be going back to a very far point in time. All of the newest updates have been installed for the OS and Office. Any ideas?
