I created a new Microsoft Team via the Teams Admin Center. Unfortunately I was not able to Access the corresponding Planner Plan in Planner nor I was able to add a new Planner Plan as a tab in Microsoft Teams. I then found this article https://social.technet.microsoft.com/Forums/en-US/90ac74bf-b2c3-4637-9af4-42a218839f1c/planner-offic.... The solution is to add the Office 365 Group owner as a member as well. Than it worked. But actually this does not make sense to me. As a owner I should also be able to have access to the Planner Plan and configure a Planner tab in Teams. Why is this? Thanks for you feedback. Maybe this is a bug.
Yes, but it is still a Bug in my opinion and should definitely not work like this by design.
I am an Admin and create a new Team in the Teams Admin Center where I define the owner of the group in the creation process
The Team is created, but the owner I defined is just an owner and not an owner and a member in the same time
The user as a owner now can't access the planner plan of the team, because he is not a member as well
When I add the User also to the list of members in O365 Admin Center, than MS Teams thinks that this user is just a member, even though he is in both roles listed. The user now can't edit the Teams setting for his team anymore.
I know have to define another owner for the group, remove the original owner from the team and add him again to the team as a member and make him an owner
Now the user is correctly a owner and a member at the same time
Workaround is to create a team with an admin as a first owner, add all members and make some owners and than remove the admin from the team. That is very confusing and time consuming.
