After a group outlives its intended purpose, group owners can delete it to free up system resources and to remove the group from being listed or displayed.
Warning: When you delete a group, you're permanently removing everything related to this group, including conversations, files, the group notebook, and Planner tasks. If you deleted the group by mistake, you can ask your IT admin to recover the group within 30 days of it being deleted.
