How do I Unregister a Personal Microsoft Entra ID?

Overview

Personal devices are most commonly registered to Microsoft Entra ID when signing into an Office 365 application (such as Outlook, Teams, or Word) and selecting "Allow my organization to manage my device" or keeping "Stay signed in to all your apps" checked.

This registers the personal computer or mobile device in the company's Entra ID environment as a Bring Your Own Device (BYOD). If you want to remove corporate access and management policies from your personal device without affecting your personal files or apps, follow the steps below.

Important Notice: Disconnecting your account revokes the device's authorization to access internal organizational resources. You may need to sign in again to web applications, but your personal files and applications will remain untouched.

Method 1: Unregistering via Client Device Settings (Recommended)

Windows 10 & 11

If you accepted the organization management prompt on a personal Windows PC:

  1. Open the Start Menu and go to Settings (gear icon).
  2. Select Accounts > Access work or school.
  3. Click on the organizational account associated with your work or school email.
  4. Click Disconnect.
  5. Confirm the disconnection prompt. (Note: You may be asked to restart your computer to complete the process.)

Method 2: Revoking Access Remotely (Self-Service Portal)

Entra Registered (BYOD) Devices

If you no longer have physical access to a personal registered device, you can disable it remotely:

  1. Navigate to the Microsoft My Account Device Portal.
  2. Sign in with your work or school credentials.
  3. Find the personal device in the list and click Disable device.

Entra Joined or Intune Managed Devices

If the device is fully Entra Joined or Managed by Intune, Microsoft disables self-service removal options on the My Account portal to prevent unauthorized unenrollment.

  • To remove these devices, you must disconnect directly on the machine via Method 1 or contact your departmental IT Service Desk to have an administrator delete/retire the device record in the admin center.
Note for Users: Disabling an Entra Registered device online revokes access tokens immediately. However, to clear cached credentials locally, you should still perform Method 1 on the physical machine when possible.

How to Avoid Re-registering in the Future

When signing into M365 apps on a personal device in the future:

  • When prompted with "Hold on while we register this device with your company" or "Allow my organization to manage my device", uncheck the checkbox or click "No, sign in to this app only".
