Uninstall Microsoft 365 and Reinstall Office 2019 via Microsoft Account
Use your Microsoft account to verify your Office 2019 license, remove the conflicting Microsoft 365 apps from your system, and download your standalone version.
Because Microsoft 365 and Office 2019 share similar installation files, installing or repairing Microsoft 365 will often overwrite the standalone versions. To fix this, you must completely remove Microsoft 365 before reinstalling Office 2019 from your Microsoft account dashboard.
Open a web browser and navigate to the Microsoft Services and Subscriptions page (https://account.microsoft.com/services/). Sign in using the email address associated with your Office 2019 license. Look under the 'Products you've purchased' section to confirm that Office 2019 is listed.
Open your Windows 'Settings' and go to 'Apps' (or 'Apps & features'). Scroll down the list of installed programs, locate 'Microsoft 365', click on it, and select 'Uninstall'. Follow the on-screen prompts to remove the application completely.
Return to the Microsoft Services and Subscriptions page in your browser. Click the 'Install' button next to your Office 2019 license. Run the downloaded setup file and follow the installation wizard to restore your Office 2019 applications.

Frequently Asked Questions
Do I need my original product key to reinstall Office 2019?
No. As long as your Office 2019 license was successfully linked to your Microsoft account during the initial setup, you do not need the physical product key. You can reinstall it directly from the Services and subscriptions page.
Why did Microsoft 365 replace my Office 2019 installation?
This usually happens if you run a Microsoft 365 installer, accidentally accept a prompt to upgrade, or perform an online repair for pre-installed Microsoft 365 apps on a new PC, which automatically overrides older standalone versions like Office 2019.
Will uninstalling Microsoft 365 delete my personal documents?
No. Uninstalling Microsoft 365 only removes the software application files from your computer. Your personal documents, spreadsheets, and presentations saved locally or on OneDrive will remain intact and can be opened as soon as Office 2019 is reinstalled.
