Sally asks "I don't want to show ALL my task, just the ones that are past due and for the next 5 days. What do I do to set it that way. In filters I can set it to show next 7 days but it won't show the past due task."
Create the custom view and create Advanced filters for:
Field Condition Value
Complete equals No
Due Date on or before 5 days from now
You can create a View using this filter in any folder that contains items flagged for follow up to show flagged items due soon or past due.
