When creating a Private Channel the error 'Cannot create private channel, at least one member should be an owner. ' is displayed. 

What does this mean and how can I resolve the error?

When creating a Private channel in Teams, there must be at least one Team Owner added as a member of the channel. This is a restriction put in place by Microsoft. 

Resolution:

• Please check the Service Definition to ensure that one person assigned to the Private Channel is an Owner of the Team.
• Go to Admin > Service Definitions > Channels > Edit the Private Channel template
• Go to the Members section, if this is blank, it will be the cause of the error. If you have only added people that are not an owner of the Team this will be the cause of the error.
  • Using {Owners.All} tranform tags will add all Owners to the Private Channel.
  • If you manage Owners using request form fields, ensure you add one of them to the members list for the Channel. {Primary Project Owners}

• Save your changes
