What you will need to do is change one setting in your mail preferences window.

How to get to my mail profiles and account preferences window:

1. From your windows operating system, Select the Start menu.
2. Control panel
3. The Mail Icon. note; the mail icon may not e visible in non classic view.
4. Under Show profiles, Select the radial button nest to " Prompt for a profile to be used".

That's it. Note: Each user must have their own profile and account created before they can access their account in Outlook.

Hope this helps.
