The user needs to remove an unwanted Microsoft 365 installation and restore their previously owned Office 2019 suite.

- Product
- Microsoft Office 2019
- Device & OS
- Windows 11
- Scenario
- A recent Windows 11 upgrade automatically installed or replaced an existing Office 2019 installation with Microsoft 365.
- Observed behavior

Ensure you have your Microsoft account login credentials handy, as you will need them to verify your Office 2019 license and download the installer.
Uninstall Microsoft 365 and Reinstall Office 2019 via Microsoft Account
The most reliable method is to completely remove Microsoft 365 using Microsoft's official uninstall tool, then manually download Office 2019 from your Microsoft account dashboard.
Simply deleting the Microsoft 365 application shortcuts will not remove the software. You must use the official removal tool to clear all background services and registry keys before installing an older Office version to prevent licensing conflicts.
Navigate to the Microsoft Services and Subscriptions page (account.microsoft.com/services) in your web browser. Log in to confirm that Office 2019 is securely linked to your account.
Download Microsoft's Office uninstall support tool (SaRA) via https://aka.ms/SaRA-officeUninstallFromPC. Run the downloaded executable and follow the on-screen prompts to completely wipe Microsoft 365 from your system.
Once the uninstallation process is complete, restart your Windows 11 computer to ensure all residual Microsoft 365 files and registry entries are cleared out.
Return to your Microsoft Services and Subscriptions page, locate your Office 2019 license, and click the 'Install' button to download the setup file. Run the installer to restore Office 2019.

Frequently Asked Questions
Will I lose my saved files when uninstalling Microsoft 365?
No, uninstalling Microsoft 365 only removes the application files from your system. Your locally saved documents, spreadsheets, and presentations will remain completely intact on your hard drive.
Why did Windows 11 replace my Office 2019 with Microsoft 365?
Certain Windows 11 updates or new system configurations come pre-loaded with Microsoft 365 trials. During an update, the system may prioritize this newer pre-installed version over your older standalone Office 2019 software.
Can I have both Microsoft 365 and Office 2019 installed at the same time?
It is not recommended. Having both Microsoft 365 and a standalone version like Office 2019 installed simultaneously can cause severe activation conflicts, default application errors, and performance issues.
