When using Teams to manage permissions across different Spaces, it's currently not possible to assign a task to someone who doesn't already have access to the Space or task.

This creates a major limitation when working across teams and departments.

For example, a Space might only be accessible to the Marketing team, but occasionally a task needs to be assigned to someone from IT or another department.

This would make it possible to use Teams and Space permissions properly while still allowing collaboration across departments.

Without this functionality, organizations must either give users broader access than necessary or manually manage permissions every time a task crosses team boundaries.
