Teams owner unable to create a Planner tab
- Applies to: Microsoft Teams
Symptoms
When trying to create a new Planner tab in Microsoft Teams, a team owner receives this error message from the Teams client:
"Failed to create the plan".
Cause
The owner isn't a member of the Microsoft 365 group associated with the team. This prevents the Planner API from triggering the plan creation.
Resolution
Add the owner as a member of the Microsoft 365 group. For more information, see Add or remove members from Microsoft 365 groups using the admin center.
