You can add groups and controls to a built-in tab. A built-in tab is a tab that's already on the Ribbon of a Microsoft Office application. For example, the Data tab is a built-in tab in Excel. When you create a custom group, it appears last on the tab, but you can move your group anywhere on the tab.

Note
You can add groups to a built-in tab, but you cannot remove built-in groups from a built-in tab.
To add groups to a built-in tab
- Right-click the Ribbon code file in Solution Explorer, and then click View Designer. - Note - If the Ribbon code file doesn't appear in Solution Explorer, you must add a Ribbon item to your project. See How to: Get Started Customizing the Ribbon. 
- Right-click any tab in the Ribbon designer, and then click Properties. 
- In the Properties window, expand the ControlId property, and then set the ControlIdType property to Office. 
- Set the OfficeId property to the control ID of the built-in tab that you want to customize. - The control ID is the name that uniquely identifies tabs, groups, and controls that are built into Microsoft Office applications. - For a list of control IDs, see Office 2010 Help Files: Office Fluent User Interface Control Identifiers. 
- From the Office Ribbon Controls tab of the Toolbox, drag groups onto the tab. - Note - Built-in groups do not appear in the designer. Therefore, the only way to determine whether you are working with a built-in tab is to examine the ControlId property of the tab. 
To position groups on a built-in tab
- In the Ribbon Designer, select a custom group. 
- In the Properties window, expand the Position property. 
- Set the PositionType property to the appropriate value: - BeforeOfficeId positions the group before a specified built-in group. 
- AfterOfficeId positions the group after a specified built-in group. 
 
- Set the OfficeId property to the control ID of a built-in group. - For a list of control IDs, see Office 2010 Help Files: Office Fluent User Interface Control Identifiers.
