Overview:
Prior to WVU migrating to SharePoint Online, students could sign in with just their Login User ID. SharePoint Online now requires students to provide a full email address in order to log in.
Problem:
WVU students trying to login to SharePoint Online may get the message "This doesn't look like a valid user ID" when they try to sign in.
Solution:
Although WVU student email addresses end in @mix.wvu.edu, students should use @mail.wvu.edu here. This is a special username used for Office 365, and is not an email address that can be used elsewhere.
Example: If your Login username is glweinrib, enter the address as follows: glweinrib@mail.wvu.edu
You will then be redirected to the West Virginia University-branded CAS (Central Authentication Service) page, which will prompt you for your Login Username and Password.
