Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello,yves alexander
Welcome to the Microsoft community!
I have realized that your Microsoft 365 is not activated.
Is the current error saying “license not found” or asking you to purchase a Microsoft 365 subscription?
It's possible that the license wasn't recognized.
You can first sign in https://account.microsoft.com/services and confirm whether you have the product of Microsoft 365.
If so ,it must be the license identification issues.
You can follow the steps below.
I suggest you use Office license removal tool to renew your license.
- Download the license removal tool.
- Open the pkg file in your Mac's Downloads folder.
3. Select Continue and follow the prompts in the setup wizard.
- If you want to start removing the licenses, select Install. You may need to enter the password for your Mac's local administrator account.
When the licensing tool is complete, select Close.
- Now open an Office app and sign in to activate with the email account associated with your Microsoft 365 for Mac license. If you're working on troubleshooting, you might need to reinstall Office before you sign in.
Once you have activated the product, restart the computer and you can get back to work.
