Symptoms/Issue: 

Are you receiving error code 700003 - Your organization has deleted this device -  when logging into M365 apps?

Environment:

Windows Computer, Microsoft 365

Cause:

  • Changed the password and changing the password removed the account from your computer.
  • Updating the device to a new operating system.
  • Accidentally disabled the device OR device has been disabled by the administrator.

Sept-by-step guide: 

If the device has been deleted,  you may need to re-register it by doing the following:

  1. Go to Settings > Accounts > Access Work or School.
  2. Select your McMaster account and if connected, select  Disconnect.  If not connected, go to Step 3.
  3. Select Connect and register the device again by going through the sign in process using your McMaster credentials.

  • Important: Make sure to complete the sign-in process, including waiting for each screen to fully load and completing all required steps such as Multi-factor Authentication (MFA). If any part of the process is skipped or incomplete (e.g., closing the page while is still loading, or skipping MFA), the device may appear connected but will not function properly.

    If the above does not work for you, please contact us and provide your device name.  See steps below to check your device name.
