Uninstall Microsoft 365 and Perform an Online Repair for Office 2021

This is the recommended approach to remove the unwanted Microsoft 365 suite and restore any shared file associations for your Office 2021 installation.

Since Microsoft 365 and Office 2021 share system registries and background services, removing one version can temporarily disrupt the other. Performing an Online Repair immediately after uninstallation resolves these software conflicts.

1
Open Windows Settings

Click the Start menu and select the gear icon to open Settings. Navigate to 'Apps' and select 'Installed apps' (or 'Apps & features' depending on your Windows version).

2
Uninstall Microsoft 365

Scroll through the application list to find 'Microsoft 365'. Click the three-dot menu icon next to it, select 'Uninstall', and follow the on-screen prompts to remove the software completely.

3
Run Online Repair for Office 2021

In the same 'Installed apps' list, locate your 'Office 2021' installation. Click the three-dot menu icon, select 'Modify', and then choose 'Online Repair'. Click 'Repair' to begin.

Windows 11 Uninstall Microsoft Office 365
Confusing Completion Message: When the repair finishes, the confirmation screen might incorrectly state that Microsoft 365 was also installed or reinstalled. You can safely ignore this message as long as your standalone Office 2021 opens successfully.

Frequently Asked Questions

Will I lose my personal files if I uninstall Microsoft 365?

No. Uninstalling Microsoft 365 only removes the application software from your computer. Your personal documents, spreadsheets, and presentations saved locally or on OneDrive will remain entirely safe and can be opened with Office 2021.

Why did my new computer come with Microsoft 365 when I already own Office 2021?

Many computer manufacturers preinstall a trial version of Microsoft 365 as promotional software. If you already own a standalone version like Office 2021, you can freely uninstall the preinstalled Microsoft 365 without consequences.

Can I run both Microsoft 365 and Office 2021 simultaneously?

Microsoft strongly advises against running multiple versions of Office on the same system simultaneously. They share background services and system registries, which often causes licensing errors, file association problems, and application crashes. It is best to keep only one active installation.
