Frequently Asked Questions

Why does my Office say expired when I just paid for it?

This usually happens because Office is still logged into your old account or caching previous license details. You need to sign out of the old account within the app and sign in with the one used for the new purchase.

Do I need a product key for my Microsoft 365 Personal subscription?

No, a product code is normally not provided for modern digital subscriptions. Your Microsoft 365 subscription is digitally linked to the Microsoft account you used to purchase it.

What is Windows Credential Manager and why do I need to clear it?

Windows Credential Manager securely stores your login data. If it holds onto your old Office Family account details, Office might automatically use those expired credentials instead of prompting you for your new ones.

Will uninstalling Microsoft 365 delete my documents?

No. Uninstalling Microsoft 365 only removes the application software itself. Your personal files, documents, and data remain safely stored on your hard drive or in your OneDrive cloud storage.
