Hi MiikkaOksanen , thanks for your reply.
Unfortunately, if I sign out, it just immediately signs me back in as soon as it launches Teams when I click Join Meeting. I have tried also signing out of my email, clearing cache in Teams (several times!) but it still logs straight back in.
When the tab opens in my browser displaying options to join in browser or on teams app - it then immediately launches Teams work or school app (with me logged back in under corporate account) and opens the meeting there before I can click on either option in browser.
However, I have now discovered that if I go back to browser and click 'Continue on Browser', it will also open the meeting in browser as a guest. This is a rather clunky work-around but at least I don't have to join every meeting under corporate account.
Hope there will soon be an update making it possible to choose which account meetings are opened in.
- Incidentally, this did not used to be a problem. I have joined meetings (in the app) numerous times in the past on this same laptop without it logging me in to the work account. I can't remember though if it was always as guest or signed in with personal account, and did not notice if it was in the work or free Teams app.
