Outlook is likely still associated with the old student license while the other apps are correctly using the Microsoft 365 Family subscription. When an app is tied to a license that is no longer valid, it can show license errors or block access to account details.
To resolve this, remove the legacy/student license association and ensure Outlook is activated with the Microsoft 365 Family account, using one of these approaches (depending on the device and how Outlook is installed):
- Sign out of all Office apps, then sign back in only with the Microsoft 365 Family account that owns the subscription. This aligns with guidance that Office apps must be signed in with the account that has the correct license.
- If using Outlook for Mac and a work/school student license was previously used, add an account that has a valid license for desktop Outlook (for home use, Microsoft 365 Personal or Family). Once Outlook is activated by a properly licensed account, additional accounts can be added regardless of license status.
- If the old student license was part of a Microsoft 365 Education subscription that has since been reclaimed, Outlook will show reduced functionality and unlicensed notifications until a valid Microsoft 365 subscription (such as Family) is used to activate it.
If Outlook continues to reference the old license after signing out/in with the correct account, uninstalling and reinstalling Office, then activating only with the Microsoft 365 Family account, will typically clear the legacy license reference.
