Frequently Asked Questions
Why does my Office desktop app say my account is not recognized?
This usually happens if you are using an incorrect email address, a typo was made during login, or the Microsoft account is not associated with an active Office Home license.
Can I use Office desktop apps without signing in?
Most modern Microsoft Office applications require you to sign in with a licensed account at least once to activate the software and unlock full editing features. Without signing in, the apps may remain in a restricted read-only mode.
What should I do if my subscription page shows no active products?
Ensure you are logged in with the exact Microsoft ID used to purchase the Office Home software. If you used a different email for the purchase, sign out and sign back in with the correct credentials. If the product is still missing, you may need to redeem your product key or contact Microsoft Support.
