Hold an impromptu meeting for your team in Teams
Getting everyone together for a meeting can take time out of your day and sometimes you need to have that meeting right now. Microsoft Teams gives you the ability to do this from within a channel by going to the Posts section of the channel and then selecting Meet: Meet Now from the upper right corner of the channel screen.
Bonus - You can click on the pull down and select "Schedule a meeting" to add a scheduled meeting to the channel for all the team members.
