Assign contexts to tasks in Outlook by doing any of the following:

  • In a task list, right click the Categories column (if visible), and select Categories…
  • Open the task, click the Categories button at the bottom right corner of the window.

Click the checkbox by each category you want to add to the task. If you want a brand new context, add it to your Master Category List by clicking that button. Adding categories there (instead of typing them) prevents you from accidentally creating duplicate categories with typos (like Errands and Errand).
