Our task pane is becoming available to users on in stages. If you would prefer to use these features, you can access Outlook Tasks in the tasks pane by toggling The new Tasks off in the top right corner. Please know, however, that Microsoft To Do does not currently support certain features available in Outlook Tasks, like the start and end dates, task status, task completion percentage, priority levels, task work hours, task colors, or the option to format text in notes. If you're signing in to with a personal Microsoft account, simply select the check mark icon to access Microsoft To Do directly from the tasks pane on.
