In the user menu that resides below your username in the upper-right corner of the application, click My Tasks.
The following page opens:
This page contains a list of tasks assigned to you.
For the description of fields and to learn more about how to manage this list and tasks from it, see the Tasks Grid guide. (The page described in the guide contains the list of tasks of all assignees but structurally is the same as the My Tasks page, except that you cannot create new tasks from My Tasks).
You can also monitor your tasks on the My Calendar page, in Tasks section of your profile, and using the Today’s Calendar and Task List widgets.
