Is the Planner Task ID globally unique?



Straightforward question but can't sift through the search result noise.


Does anybody know if the Task ID property of task in MS Planner is globally unique? Or is only unique within a given Plan?



I have a SQL table recording all tasks from a plan and want to add multiple plans to the table. Do I need to change the primary key to Plan_ID and Task_ID or am I safe to just use Task_ID?

Hi @Charles_John


I have made a test on my side and I couldn't find any documentation telling about it.


The task id would always with a type as "gsbv30NmtE6mGvXJJP85z8kAI8KD" and I guess it is globally unique.


If you want to make sure there are no problems,you could change the primary key to Plan_ID and Task_ID.



Best regards,
