Since the challenge update, our regular weekly workplace step challenge has suddenly seen upwards of 100 people join. Will this running challenge have to be reset to be made private?
If your employer is running a specific Employer Sponsored Challenge, they will be able to change the settings. However, if you are creating challenges through the Go365 Mobile app, you will need to select that the challenge is private and send out individual invites to the team members. There is no way to restrict members from joining Community Challenges or Teams.
