A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
If the school account works in Office on the web but not in the desktop app, the most likely causes are:
- The account does not have a desktop Office license assigned.
- Sign in to the Microsoft 365 Subscriptions page with the school account.
- Check whether The latest desktop version of Office appears under the license details.
- If it is missing, the school’s Microsoft 365 administrator must assign the correct education license.
- Cached sign-in or identity data on Windows is blocking desktop activation.
Try this in order:
- Close all Office apps.
- Go to Settings > Accounts > Access work or school.
- If the school account is listed, select it, choose Disconnect, then connect it again with the same school account.
- Open Control Panel > User Accounts > Credential Manager.
- In Windows Credentials and Generic Credentials, remove entries related to the Microsoft 365 school account.
- Restart Windows.
- Open Excel and sign in again with the school account.
- Office needs to refresh its activation state.
- Open an Office app.
- Go to File > Account > Update Options > Update Now.
- Then sign out and sign back in with the school account.
- If the device previously used another Microsoft account, account conflicts may be causing the problem.
- In Settings > Accounts > Access work or school, remove unused work or school accounts.
- Reconnect only the account that has the school license.
If the license check shows web-only access, this is not fixable from the device. The school IT administrator must assign a license that includes desktop apps.
