I have a private GSD board in Trello. I had previously linked my Microsoft Teams account to Trello so that I can add a channel in teams for viewing particular Trello boards.
I have a private board I use to keep track of my own tasks that is not shared with any team or group.
When I add a card or conduct any activity on this board - an email notification is sent to a group email inbox in Outlook - how the hell is that happening? I have never associated this email alias with anything in Trello.
What is it about Private Board that is so hard to understand - if I wanted this shared with a team - I would add it to a team board!
