Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Jayne.
1
Open the Settings App.
Go to Apps - Installed Apps.
Scroll down to find Microsoft Office and uninstall Office from there.
Restart (not shut down) your PC.
2
Then, log into your Microsoft account on this link.
https://account.microsoft.com/services/
There, you will find your Microsoft 365 subscription and can install Microsoft 365 from there.

If that does not resolve the problem.
Open Word.
Go to File - Account.
Click the Switch Licence button, and from the resulting list, you should be able to switch to your Microsoft 365 subscription.
