I have two simultaneous tasks and the same resource assigned to them, which naturally produced an overallocation in MS Project 2010.
The leveling tools on the Resource tab, for some reason, are not fixing the overallocation. Both tasks are manually scheduled and the Level Manually Scheduled Tasks option is checked under Leveling Options.
I can fix the overallocation manually in the Team Planner or by splitting the longer task around the shorter one, or by changing the tasks to Auto-Scheduled, but I thought Project would take care of the allocation for me using one of the Leveling tools on the Resource tab.
