New Teams Channel Calendar App Makes Channel Meetings Easier to Access

CamillaAndersson I don't see that happening in my tenant. I created a new team, added some guest accounts, and scheduled a meeting with the channel calendar app. The only person who received anything was the meeting organizer, who had the meeting entered in their calendar. No guest received an invitation.

Is the group/team you are using an old one or recently created? If it's older than a couple of years, it might have different settings as Microsoft has changed things in this area in the past.
