Fix Office 2016 Appearing as Microsoft 365 After Windows Updates
Question details
The user's Office 2016 Professional Plus installation is displaying as Microsoft 365, triggering an unwarranted product notice warning.

- Product
- Microsoft Office 2016
- Device & OS
- Windows 10
- Scenario
- Opening Office applications after a recent Windows update or reactivation process.
- Observed behavior
- A Product Notice warning banner appears claiming a Microsoft 365 subscription issue, even though the File > Account dialog confirms that the Office Professional 2016 license is actively licensed.
Ensure you have your original Microsoft Office 2016 Professional Plus product key available before uninstalling any potentially conflicting applications.
Remove Conflicting Office Installations and Verify License
Check your Windows system settings for duplicate or conflicting Microsoft 365 installations and confirm your 2016 activation status within the application.
Windows updates or pre-installed trials can sometimes cause Microsoft 365 to run alongside your standalone Office 2016 installation. This overlap confuses the licensing service, causing the Microsoft 365 warning banner to display in your 2016 apps.
Open any Office 2016 application, such as Word. Click on 'File' in the top left corner, then select 'Account'. Under Product Information, verify that 'Microsoft Office Professional Plus 2016' is listed as Activated.
Press the Windows key + I on your keyboard to open Windows Settings, then click on 'Apps' to view your installed programs.
In the 'Apps & features' list, scroll down or use the search box to look for 'Microsoft 365' or duplicate entries of Microsoft Office suites.
If you find a Microsoft 365 entry that you do not have a subscription for, click on it and select 'Uninstall'. Follow the on-screen prompts to remove it, then restart your computer.

Switch to WPS Office to Avoid Licensing Glitches
If persistent activation warnings, duplicate installations, and confusing product banners are disrupting your productivity, consider switching to WPS Office. It provides a lightweight, free alternative that completely avoids subscription conflicts while offering everything you need.

Frequently Asked Questions
Why does my Office 2016 say Microsoft 365?
This happens when a Windows update installs Microsoft 365 background services or when a pre-installed Microsoft 365 trial on your PC overlaps with your Office 2016 installation, causing the interface to display Microsoft 365 prompts.
Will uninstalling Microsoft 365 delete my Word documents?
No, uninstalling the Microsoft 365 application from your Windows Apps & features menu only removes the software program. Your personal files, documents, and data will remain safe on your hard drive.
How do I permanently get rid of the Product Notice warning banner?
You can resolve this by uninstalling any overlapping Microsoft 365 apps from Windows Settings. If no overlapping apps exist, signing out of your Office account under File > Account and signing back in will often clear the cached license warning.
