If the Microsoft 365 subscription expired, the Office apps from that subscription can remain installed but go into Reduced Functionality Mode. In that state, documents can usually be opened and viewed, and often printed, but creating, editing, or saving changes is blocked until the subscription is renewed.
For Office Home 2024 on a new PC, the most likely fixes are:
- Confirm the Office 2024 license is on the Microsoft account used in Office
Sign in to Services & subscriptions and verify Office Home 2024 appears there. - If Office 2024 is active, remove old Office licensing traces and reactivate
On Mac, Microsoft provides a License Removal Tool for removing the old Office license, then reopening an Office app and signing in with the account associated with the new Office. - On Windows, uninstall the older Office installation and reinstall Office 2024
If both Microsoft 365 and Office 2024 are present, activation conflicts can cause Unlicensed Product or prevent normal use. Use the uninstall troubleshooter to remove Microsoft 365, Office 2021, Office 2019, or Office 2016 from the same Windows PC, restart, then reinstall Office 2024 from the account that owns it.
Note: uninstalling Office removes the apps, not Word or Excel files. - If Office 2024 is installed but shows the wrong version or licensing state, install the latest Office updates
Microsoft notes that Office 2024 can sometimes appear as an earlier version when the same Microsoft account has both Office 2024 and an earlier Office license. Installing the latest Office updates is the first fix. - If Office 2024 still appears as an earlier version on Windows
Close all Office apps, go to%LocalAppData%\Microsoft\Office\Licenses, delete the folder named 5, then open an Office app and sign in again.
Warning: deleting licensing data affects Office activation state and should be done only after updating Office and closing all Office apps. - If documents are stored in OneDrive, check storage status
After a Microsoft 365 subscription expires, OneDrive storage returns to 5 GB. If usage is over the free quota, uploading and syncing can be affected, and existing files can become read-only. If the files were only in OneDrive and storage is over quota, reduce storage usage or renew the subscription.
If the PC is Windows, the most direct path is:
- Verify Office Home 2024 is listed in Services & subscriptions.
- Remove older Office installations with the uninstall troubleshooter.
- Restart the PC.
- Reinstall Office 2024 from the same Microsoft account.
- Open Word or Excel and try File > Open on one of the affected documents.
If the PC is Mac, verify the license, run the License Removal Tool, then sign in again in an Office app and check for updates.
