Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello Ripa Kalamo,
If your Microsoft 365 free trial has expired, the desktop Office apps will remain unlicensed until they're activated with a valid license. Unfortunately, this cannot be manually unlocked.
You can check whether you already own an Office license by signing in at https://account.microsoft.com/services with the Microsoft account you previously used.
If no active subscription or purchased Office license appears there, you'll need one to restore full desktop functionality. Alternatively, you can use Word, Excel, and PowerPoint for free in your browser at https://www.microsoft365.com/.
