Hello @Rockycobb Raymond ,
You can open MS Teams app on PC/laptop using multiple accounts in parallel, but not under single desktop app.
You can open the second account in web browser and install the site as an App.
- Login to Teams desktop app with Account 1. You will enjoy the features of Teams app.
- Open Chrome Browser and create Profiles for Account 2, Account 3, so on & so forth.
- Login to https://teams.microsoft.com/ using Account 2.
- Go to Setting & More (...) > APPS > Install This site as an App
- Pop up window appears where you can rename APP as needed
- You will now see Teams for Account 2 is open as PWA.
- You can pin this to your Taskbar or create as shortcut and use both Account 1 & Account 2 simultaneously.
