Deleting credentials from your computer
Deleting credentials means that old Office logins are deleted from your computer. These can be logins from another organization or logins with your own other Office IDs that prevent school IDs from logging into Office applications.
You can also use this guide if your employment or study relationship ends, so your old IDs won’t be stored in Office applications.
1. Open the Start menu and search for Control Panel. Open the Control Panel.
2. Click Manage Credentials.
3. Click Windows Credentials.
4. Here you will find all the identification and password information stored on the machine. Clear all of the Office and Microsoft-related sections from the general credentials. Open the credentials from the button on the right and click Delete.
Office programs will then ask you to log on again the next time you start.
