Check the Sort Order
If you don’t see your oldest, most-neglected tasks at the top and more-recently-changed tasks at the bottom, you probably clicked a column header by accident. (Outlook breaks the sort when you do that.) See sort instructions in Weekly Review list setup.
After you set up your Weekly Review view, it will be a permanent part of your Current View options. Select the Weekly Review from that list by clicking the radio button next to it.
This list shows you tasks without active hard dates that you may not looked at recently.
