Uninstall Office 2016 and Repair Microsoft 365

Manually remove the older Office 2016 installation and run a repair on Microsoft 365 to restore full functionality and features.

Repair Microsoft 365

4
Verify Microsoft 365 Features

Frequently Asked Questions

Why does Office 2016 show as active when I have a Microsoft 365 subscription?

This typically occurs because the older perpetual license (Office 2016) takes precedence in the Windows registry or local license cache when both versions are installed simultaneously.

Can I use the Microsoft Support and Recovery Assistant (SaRA) to fix this?

While SaRA is helpful for complete uninstallations, it often removes all installed versions of Office. If you only want to remove Office 2016 and keep Microsoft 365, manual uninstallation via the Control Panel is recommended.

How can I easily tell if I am using Microsoft 365 or Office 2016?

Open a new document in Microsoft Word and look for cloud-based tools like 'Dictate' or 'Editor' on the Home ribbon. If these tools are visible, you are currently using the Microsoft 365 version.
