How to Resolve Microsoft 365 and Office 2016 Activation Conflicts
Question details
The user needs to resolve an issue where both Microsoft 365 and Office Professional Plus 2016 are installed, but the system identifies Office 2016 as the active product.

- Product
- Microsoft 365, Office Professional Plus 2016
- Device & OS
- not provided
- Scenario
- Managing multiple Microsoft Office installations and ensuring the correct Microsoft 365 subscription features are active.
- Observed behavior
- Both versions appear on the computer, and the Office Account page incorrectly defaults to showing Office Professional Plus 2016 as the activated product instead of Microsoft 365.
Verify your active Microsoft 365 subscription status by logging into your Microsoft account online to ensure your license is valid before altering local installations.
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.
It is highly advised to avoid using the automated Microsoft Office removal tool for this specific task, as it will indiscriminately remove all Office installations, including your Microsoft 365 apps.
Press the Windows key, type 'Control Panel' in the search bar, and select 'Programs and Features' or 'Uninstall a program'.
Scroll through the list of installed programs, locate 'Microsoft Office Professional Plus 2016', right-click it, and select 'Uninstall'.
In the same program list, find 'Microsoft 365', right-click it, select 'Change', and choose 'Online Repair' to fix any broken registry keys or file associations.
Open Microsoft Word and check the Home tab for Microsoft 365 exclusive features, such as 'Editor' or 'Dictate', to confirm the activation is successful.
Keep the Current Installation (If Functional)
If your current Office installation works perfectly and you do not require Microsoft 365 exclusive features, leaving the setup unchanged is a safe alternative.

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.
