How to Fix Microsoft Teams Duplicate Login Error [Guide]
Login errors in an app often prevent you from using it altogether. Some apps allow users to use them with or without an account but Microsoft Teams is not one of them. With Microsoft Teams users become a part of teams, share documents, having online meetings and for all that, an account is required. This means that if Microsoft Teams is an integral part of your workflow you can’t log in to it, you’re not going to get anything done until you fix the problem.

This means that the users are logged into their accounts from the web interface and are trying to login to a desktop application as well. There are plenty of apps that can work in this same setup but Microsoft Teams sometimes throws an error. Here’s how to fix it.
