How do I "forget" a login name? I am using a computer at work that originally was used by another employee. When I open Outlook, the login box only shows her user names. I have to retype in my user name to login. The small "Forget" box next to the user name is grayed out, so I cannot use that. I would like my user name to appear in the drop down user name list, or get rid of the old user's name and have my user name appear when ever I sign into my desk top Outlook. this is not a problem in Outlook 365..
The computer's operating system is Windows 10.
