We’ve already looked at customizing the Office 2010 ribbon in detail, but this time we’re going to be a little more specific. The Developer tab is a pre-built custom tab that by default has a good variety of advanced actions, and enabling it is simply a lot faster than searching for and adding these to your own tab. Although the screenshots below show the steps in Outlook 2010, the steps are 99.9% the same for Excel 2010 and Word 2010.
In your Office 2010 program, Click the File menu and Select Options. In our example we are using Outlook 2010.
From the Options window, Click the Customize Ribbon tab and then Check the box for Developer under the Main Tabs section. Click OK to save changes.
The developer tab should now show up on the ribbon in your Office 2010 application. If you ever decide that you don’t like the developer tab you can easily disable it by reversing the above step.
