Includes tools to launch multiple Teams.


One of the problems that occurs when you start using Teams is that you cannot easily switch between organizational accounts. You can do this in the mobile app, but not in the PC app.

You have to log out and log back in. This is very inefficient and frustrating.

Research into this issue shows that there are ways to install it as an app in Edge, or to use tools such as Rambox to switch. However, the reality is that all of these methods only switch the web version of Teams. Therefore, they cannot be used by organizations that restrict the use of the web version.

The solution is to launch multiple Teams app versions. However, it is usually not possible to launch multiple Teams. I would like to introduce a tool that allows you to launch multiple Teams: Multi Microsoft Teams is OSS which solves the problem by allowing you to launch multiple Teams. Currently, it is only available for Windows.

Multi Microsoft Teams

Simply download the file from GitHub, unzip it, and run it.

The startup screen is quite simple.

In NEW PROFILE, name the second profile to be activated and SAVE.

You can register multiple Teams in the same way.

Select the Teams profile you wish to launch and click LAUNCH TEAMS.

When launching, you will be prompted to log in using your organization’s account.

The following is a case where three profiles have been registered and each profile has been activated.

Each Teams launched is also displayed in the taskbar. They are also resident in the tray.

If you want to delete it, use the Delete key. Double-click to Disable.

If Teams cannot be started successfully, restarting Teams, re-logging in, etc., fixed the problem.


Multi Microsoft Teams is a very useful tool and you should use it.
