Joining a meeting with a specific Teams account

Hi, yeah it's not ideal to use multiple account on Teams desktop app right now. What people usually do here is using Teams with their browser/browsers and sometimes also with InPrivate / Incognito sessions. What I could suggest is that you choose to manually sign out from Teams and then sign in only with the account you're about to use (i.e. the account the invite has been sent to) instead of switching account from the top right corner. Make sure the account that you don't want to use isn't added under the W10 account settings, if so remove it from there and try again.

If you can't seem to get a clean sign out or the possibility to choose what account to use when starting Teams again you can run this script. Just copy and paste into PowerShell and hit enter. It will clear all auto-start settings https://docs.microsoft.com/en-us/microsoftteams/scripts/powershell-script-teams-reset-autostart
