Hi, I was working on to get all tasks from Microsoft To Do lists. The documentation does not say about it. But I figured out a way to get all task lists from Microsoft To Do. Here is the way : POST /me/todo/lists/Tasks/tasks POST /users/{id|userPrincipalName}/todo/lists/Tasks/tasks GET /me/todo/lists/Tasks/tasks GET /users/{id|userPrincipalName}/todo/lists/Tasks/tasks 😃
