Remove 250 task limit per person per plan.
Currently, there is a 250 task limit per person per plan. The error states “You've run out of space! Delete some old tasks and projects to continue creating new ones.” Removing completed tasks defeats the purpose of using Planner as a historical task tracker if resources are limited to 250 tasks.
This limit has been removed – users can now have thousands of tasks assigned to them.
We’re continuing work around performance and actively monitoring how many users hit this limit. So far, we only have seen users with unchecked Flows/automated task assignments hitting this limit.
We are planning on publishing formal documentation around all of our Planner limits once we’ve completed more performance work, but don’t have anything to share at this time.
