Have MS Office 2007 but want MS Office 2003 toolbars

Previous solution is right in that you can't make it look like 2003. What I have done is add frequently used commands to the toolbar. It will somewhat mimic 2003 and get you through the change over until you get used to finding the commands you are looking for.

To add commands to the toolbar:
Mouse over the 'quick access toolbar' and right click
Select 'customize quick access toolbar'
You will have a comprehensive list of commands you can add to the toolbar

well. in this case the new look it the most problematic issue for any user taht previwsly had office xp, office 2003. you can't change the apparience. just the colors. if at least you want to use your favorite color. this is how !

You can customize the appearance of the Office Fluent Ribbon in Microsoft Office Access 2007, Microsoft Office Excel 2007, Microsoft Office Outlook 2007, Microsoft Office PowerPoint 2007, or Microsoft Office Word 2007 by selecting one of the available color schemes.

example

1. Click the Microsoft Office Button, and then click Word Options at the bottom of the window.
2. Click Popular, and then click the Color scheme that you want.
