How to Uninstall Microsoft 365 Office

Office provided through Microsoft 365 (organizational accounts) is subject to an installation limit of up to five devices per user.

When replacing a PC, if you do not properly deactivate the old device, you may see an error stating “You’ve reached your device limit.” For this reason, proper removal is essential.

This article explains the correct uninstallation procedure to reduce the device count.

Important Notes

Simply removing Office from the PC does not always reduce the device count.
Be sure to deactivate the device from your Microsoft 365 account first.

Step 1: Deactivate the Device from Your Microsoft 365 Account (Required)

Access the following URL and sign in with your organizational account:

2. Select the target PC

Once completed, that PC will no longer count toward the installation limit.

Step 2: Uninstall Office from Windows

1. Open Settings
2. Select Apps
3. Go to Installed apps
4. Select Microsoft 365 Apps (or Microsoft Office)
5. Click Uninstall
