The Teams channel calendar app highlights meetings scheduled for a calendar and makes it easier for team members to attend these events. Meetings for all channels in a team are stored in a single calendar, so the app applies a filter to display the meetings belonging to the channel it is installed into.
Teams makes it easy to schedule meetings for people to attend online. You can create meetings with Outlook or the Teams calendar app. Notifications go to those invited, but you can’t really invite a channel from a team. If you add a channel to a meeting, that’s where the online gathering takes place. So who gets notified then?
