- Scenario

Click the Start menu, type 'Control Panel' into the search bar, and press Enter to open it.
Navigate to Programs > Programs and Features. Locate any entry for 'Microsoft 365' in the list, right-click it, select Uninstall, and follow the on-screen prompts.

Frequently Asked Questions
Why is my Office 2016 showing as an expired Microsoft 365 subscription?
This typically occurs if a pre-installed Microsoft 365 trial was on your computer or if you temporarily used Microsoft 365. The system prioritizes the newer subscription software, which overrides the activation status of your older permanent license like Office 2016.
Where can I find the Microsoft account linked to my Office 2016 product key?
You can verify your associated account by logging into the Microsoft Account Services and Subscriptions page online. Your purchase history and linked Office 2016 license will be listed there if it is the correct account.
Will running Quick Repair delete my Office files or documents?
No, running a Quick Repair from the Control Panel only fixes and replaces corrupted software installation files. It will not delete, alter, or affect any of your personal documents or data.
