I cannot seem to determine how to change the font color in the Calendar View. I have four tasks from the Gantt view that I can change there but I cannot go over to the Calendar view and change those same four tasks.
Formatting the font works differently in the Calendar view. You can change the text color, but it is sort of all or nothing. Try right clicking on a task, then select Text Styles, choose Non-Critical tasks and change the font color to Blue. Click on OK. All non critical path tasks are now blue.
Probably not exactly what you want, but perhaps this helps!
