Outlook for Windows Fails to Authenticate After Password Change

When Outlook refuses to connect to the mail server (especially after a recent password change) it may be necessary to delete old information that Outlook is "holding onto".

To fix this issue, follow these steps:

1. Close all running instances of Microsoft Outlook.
2. Go to Start >> Control Panel.
   
   
    
3. In the upper right corner, click the View By pulldown menu and choose "Large" or "Small" icons. 
4. Open the Credential Manager control panel.
   
   
    
5. Under Generic Credentials, find your Outlook login information. The proper listing will begin with "Ms.Outlook" and also contains your Xavier email address. Click the adjacent down arrow to expand the contents.
   
   
    
6. Click on Remove From Vault, click Yes to confirm, then close the panel.
   
   
    
7. Re-open Outlook. It may take several minutes to get past the Outlook splash screen. If you are at any point prompted for your username and/or password, provide them. Be sure to check the Remember My Password box, unless you want to be prompted for it every time Outlook tries to authenticate.
