Same issue here. Entire Team gets an invite, when they only want to invite certain people (or Channel). I understand that Teams is connected to O365 Groups and the invite is going through the group. The only workaround so far is to go into Outlook via O365 and disable all notifications for that group (https://blogs.technet.microsoft.com/skypehybridguy/2018/01/06/why-do-i-receive-invites-to-channel-meetings-in-microsoft-teams-mystery-solved/)
Not ideal, but it would be great if that setting could be changed globally rather than tell 106 users to do that.
