Organize your in-box by categorizing your emails. 

Have you ever lost track of an email that needed to be responded too because you had too many emails in your inbox?

You can assign a category to each of your emails and then group your inbox by categories and all your emails referring to a particular project or work activity are grouped together.

The inbox below contains 75 emails but by categorizing them, you are less likely to overlook one.

To categorize an email, right click on the email and select Categories.  Outlook comes standard with default categories but you can add ones that are more specific to your projects.  To add a category, from the Categories list click Master Category List.  Type in your new category and click ADD.  When you have entered all your new categories click OK and OK again. 

To have your inbox show the categories, click VIEW, Current View, Customized Current View.  In the View Summary box click Group By and select Categories in the Group Items By box.  Click OK and OK again
