Solution 1Recommended

Sign Out of Duplicate Devices via Microsoft Account Portal

Resolve the duplicate device issue by signing out of the redundant sessions directly from the Microsoft account management page.

Duplicate device entries usually occur due to system updates or multiple sign-in events on the same machine. Removing these duplicates from the online portal only revokes application access and has no impact on your saved files.

1
Access the Microsoft Account Portal

Open your web browser and navigate to account.microsoft.com. Sign in using your Microsoft 365 credentials.

2
Locate Your Devices

Navigate to the 'Devices' section on your account dashboard to view all hardware currently associated with your Microsoft 365 subscription.

3
Identify and Sign Out of Duplicates

Look for the duplicate entries of your Windows device. Click 'Sign out' or 'Remove' next to the duplicate entry. If you are unsure which one is active, you can sign out of both.

4
Refresh the Account Page

Refresh your browser page to verify that the duplicate listing has been successfully removed from your account.

5
Re-authenticate on Your Computer

If you signed out of the active session by mistake, simply open any Office application on your computer and sign back in when prompted.

Data Safety Guarantee: Signing out of a device only removes its authorization to connect to Microsoft 365 services. Your local files, documents, and data stored in OneDrive will not be deleted or lost.

Frequently Asked Questions

Will removing a device from my Microsoft 365 account delete my files?

No, removing or signing out a device from your Microsoft account only revokes its access to Microsoft 365 services. It does not delete locally stored files or data saved in your OneDrive.

Why is my Windows computer showing up twice in the device list?

Duplicate device entries often occur after major Windows system updates, hardware changes, or if you sign out and sign back into Office applications multiple times without clearing previous sessions.

What happens if I accidentally sign out of the active device instead of the duplicate?

If you sign out of the active device, you will simply be prompted to sign back into Microsoft 365 on that computer. Enter your email and password to restore access immediately.

How long does it take for a removed device to disappear from the Microsoft list?

Usually, the device disappears immediately upon refreshing the page. However, it may sometimes take a few minutes for the Microsoft servers to sync the updated status.
