Product: Microsoft 365

Before you start

Frequently Asked Questions

Why does my school account work online but not in desktop apps?

Many schools purchase 'A1' educational licenses, which only provide access to the web-browser versions of Office applications. To use installed desktop apps, your account needs an 'A3' or 'A5' license assigned by your school.

How do I clear cached Microsoft 365 credentials in Windows?

You can clear cached credentials by opening the Windows Control Panel, navigating to 'Credential Manager', selecting 'Windows Credentials', and removing any entries that start with 'MicrosoftOffice16' or 'msteams'.

Can I still edit my school documents if the desktop apps won't sign in?

Yes, you can edit your files using the Microsoft 365 web apps in your browser, or you can download the files locally and use a free desktop alternative like WPS Office to edit them without signing in.
