Hi Rao Andavolu,
1
Open Word.
At the top right of Word, log out of Office.
Restart (not shut down) your PC, then log back into Office, is your subscription then recognized correctly.
2
If not, log into your Microsoft account on this link, check the expiry date listed on your subscription, is that listed correctly.
https://account.microsoft.com/services/
If the subscription expiry date is listed correctly on your account:
Open the Settings App (gear icon on your Start Menu)
Go to Apps - Installed Apps or Apps and Features
Then, scroll down to find Microsoft Office or Microsoft 365.
Select that and choose Modify - Online Repair
That should fix any issues with your Office Installation.
