Question details
The user needs to resolve an issue where their Microsoft 365 applications unexpectedly display a not activated status after functioning correctly for months.

- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Opening a Microsoft 365 application like Word or Excel and finding it deactivated.
- Observed behavior
- The software reports that it is not activated, restricting access to features and editing capabilities, despite previously working fine for several months.
Ensure you have your Microsoft account login credentials handy, specifically the email and password used to purchase or register your Microsoft 365 subscription.
Verify Subscription and Update License in Office
Check your Microsoft account online to ensure your subscription is active, then force a license update within the Office application.
Often, Office simply loses sync with your Microsoft account or your billing details need to be updated online.
Go to https://account.microsoft.com/services in your web browser and sign in with the Microsoft account associated with your purchase to verify that your subscription is active.
Launch Microsoft Word or Excel on your computer.
Click on 'File' in the top-left corner and select 'Account' (or 'Office Account') from the left-hand menu.
Click the 'Update License' button. You may need to sign out of your current session and sign back in using the correct purchasing account.

Run the Microsoft Support and Recovery Assistant
Use Microsoft's official troubleshooting tool to automatically diagnose and reset corrupted activation states.
Verify License Assignment (Work or School Accounts)
If you are using a business or education account, your IT administrator may need to reassign your Microsoft 365 license.

Frequently Asked Questions
Why does my Microsoft 365 subscription suddenly say expired when it shouldn't?
This typically happens if auto-renew failed due to an expired credit card, or if you accidentally signed into Office with a different Microsoft account that does not hold the active subscription.
Will I lose my files if Microsoft 365 is not activated?
No, your local files are safe. An inactive Microsoft 365 product enters 'View Only' mode, meaning you can still open and print documents, but you will not be able to edit them or create new ones until the software is reactivated.
How do I check which Microsoft account is linked to my current Office software?
Open any Office application like Word, go to File > Account, and look under the 'User Information' and 'Product Information' sections to see the currently signed-in email address.
