If you are unable to sign into Teams or any other Office 365 application with the following error message:

Or you see the following error in Teams

This happens because your University of Southampton account is associated with your personal device. To remove this please click on the Windows Start Menu and click on the Settings button (gear wheel)

Next, Click on the Accounts button

Then click on the Access Work or School accounts button, you will see your University account listed here.

Click on the account

And select the disconnect button

Click on Yes and the account will be logged out from your device.

Once the account has been removed, launch Microsoft Teams again. You will be asked to enter your credentials. When you see the following screen DO NOT CLICK ON OK

 

 

 

Instead, Untick the “Allow my Organisation to manage my device” option and click on the bottom right option "No, sign in to this app only"

 

 Now click on OK and Teams will launch as normal.

The reason why this happens is because during the logon screen of Teams or any other Office365 application you see the prompt above and “enroll” your personal device onto the University’s Office365 portal. You can see this by going navigating to https://myaccount.microsoft.com/

Once logged in you can navigate to “Devices” and see what personal devices you have enrolled.

If you click on the disable button, your device will be marked as disabled and you will get the error described in the first screenshot.

THE ONLY WAY TO FIX THIS ISSUE IS TO LOG INTO THE PC AND DISASSOCIATE YOUR UNIVERSITY ACCOUNT FROM THE PC AS SHOWN IN THE STEPS ABOVE.
