try go to: C:\Users\YOURUSERNAME\Appdata\Local\Microsoft\Outlook Now you remove the Default Outlook Profile.
When you start Outlook up Again, it will need to sync your emails etc, it can take a Little while, but it should fix the problem.
Thanks for your help, but google says "the web page cannot be found" when I type into the browser what you just advised.
Its not a browser you open. go to Start -> Computer, and then in the top of the window you see something like this ">Computer >" press on a blank spot there. now enter what i said, and remember "YOURUSERNAME", shall be replaced with your username
It should solve the problem.
