The gHacks blog points out a great, but lesser-known feature in Microsoft Outlook: You can sort by multiple columns at the same time with an easy trick.
All you need to do is hold down the Shift key while clicking on the column header for one column, and continue to hold the key down while you click on another column. This can be very handy for more advanced sorting on the fly—for instance, you could sort by sender, and then by message size to find the biggest file from a particular sender. It’s one of those tiny, but very useful tricks that we love to find.
