Restoring Groups to an Arrangement

In my Inbox, I chose the Size option from the View, Arrange By menu, but I got one long list instead of the logical groupings I usually see. What happened?

You must have inadvertently cleared the Automatically Group According to Arrangement option on the Group By dialog box for the current view. This can easily happen if you tinker with view settings. To restore the groups, choose View, Arrange By, and click Show In Groups.
