Managing presence indicators such as Available, Busy, or Away to reflect user availability
Hi pachakutiq,
I'm Nik, an independent advisor here to assist you with this.
You can set "Appear offline" when you want to indicate others that you're not signed in to Teams, so will not be responding until you're back online. You'll still receive notifications if anyone messages you.
To answer your question related to the meeting - Yes, you will appear in meeting participation list if joined, and if not join in that case also you will be shown in absentees and ' Request Others to Join' list. Just that your presence status will show as "Appear offline", but that stops you from receiving and participating any activity in Teams.
I hope this helps!
Regards
Nik
