How to run multiple sessions of Teams at the same time.
Several customers and colleagues have asked me how I can run multiple sessions of Teams at the same time. So, I decided to write a short guide.
In the new Edge, the one based on the Chromium engine, you have the option to have multiple profiles.
Create one profile for each account you want to use with Teams. I have three; work, personal and a lab user. To create a profile, click on the profile image in the upper right corner  and select ‘Add a profile’ . Each profile you create can have their own favorites based on the need for that user .
Once you have created your profiles, select one and browse to Teams.Microsoft.com . It should either just log you on or prompt you with which account to use. When you’re logged in to Teams click on the three dots in the upper right corner . Go down to ‘Apps’  and select ‘Install this site as an app’ . Give the app a name e.g. “Family”. Do this for all your profiles.
Click on the start menu and go to ‘All apps’ . Browse to your new app  and right click and select ‘Pin to Start’ .
Arrange the tiles as you want . When you click for example the ‘Family’ tile, it opens with that account. Click on the other tiles to open multiple sessions of Teams .
