Disconnect and Reconnect Your Work or School Account

Removing the disconnected organizational account from your local Windows settings and signing back in will force the device to re-register with your organization's management system.

Signing out and signing back into the Microsoft 365 app alone usually provides only a temporary fix. To permanently resolve error 700003, you must remove the device registration from your Windows settings so it can properly re-sync with Microsoft Entra ID.

1
Open Windows Settings

Click the Start button and select the gear icon to open the Windows Settings application.

2
Navigate to Account Settings

Click on 'Accounts' from the main menu, then select 'Access work or school' from the left sidebar.

3
Disconnect the Organizational Account

Locate and click on the organizational account associated with the Microsoft 365 error. Click the 'Disconnect' button and follow the on-screen prompts to remove it from your device.

4
Restart and Sign In

Restart your computer. Open any Microsoft 365 application (such as Word or Excel) and sign in again with your work or school account to re-register the device.

Disconnect and Reconnect Your Work or School Account
Re-registration Successful: By disconnecting and signing back in, your device generates a fresh registration token with your organization's network, effectively clearing the 700003 error.

Frequently Asked Questions

Why did my organization delete my device from Microsoft 365?

Devices are usually removed from Microsoft Entra ID or device-management portals due to prolonged inactivity, routine administrative cleanup, a change in security policies, or if the device was reported lost or replaced.

Can I fix error code 700003 without contacting my IT administrator?

Yes, in many cases you can fix it yourself by going to Windows Settings > Accounts > Access work or school, disconnecting your account, and signing back in. If this does not solve the issue, administrator intervention is necessary.

Will disconnecting my work account delete my personal files?

No. Disconnecting your work or school account only removes the organization's access token and policies from your device. Your locally saved personal files and documents remain completely unaffected.
