How we are going to do this?

Create a new user in windows, and then run another version of teams with the newly created user’s identity

Steps:

1. Create a new User, call it Teams:

Win + R –> lusrmgr.msc

2. Login as the new user

Ctrl + Alt + Del –> Switch User

3. Download and install ‘Teams on the new user account’

4. Run teams and sign in as ‘Company 2’

5. Close Teams

Exit Teams, it if it still running from the system tray

6. Switch back to the original user account

Ctrl + Alt + Del –> Switch User

7. Run a new instance of teams as the new user

runas /user:Teams "cmd.exe"

and in the new command prompt, which should be running as the ‘Teams’ user…

C:\Users\Teams\AppData\Local\Microsoft\Teams\Update.exe –processStart "Teams.exe"
