Overview

This article shows what to do if Outlook keeps asking for username and password. The most common cause is having old credentials stored in the credential manager.

To clear the credential manager:

1. Open the Control Panel from the start menu. If using Windows 8, right-click on the start button and select Control Panel.
2. In the View by drop-down in the upper right, change it to Small icons.
3. Select Credential Manager, then Windows Credentials.
4. Under the Generic Credentials header, look for Outlook credentials. They will look like MS.Outlook:netid@usf.edu, or MicrosoftOffice15_Data:SSPI:netid@usf.edu.
5. Select the drop-down arrow next to the credential, and select Remove.
6. Close and re-open Outlook. Enter your credentials when prompted, using your email address as the username. Ensure that you check Remember my credentials.
