Changing the Outlook Sidebar Colors
Coveo .NET Front-End 12.0.235+ (June 2013)
Note: It is also possible to create a custom Outlook Sidebar color scheme (see Creating a Custom Color Scheme for the Outlook Sidebar in the Windows Registry).
To change the Outlook Sidebar colors
In Microsoft Outlook, from the menu, select Coveo > Options.
In the Coveo Desktop Integration Package Options dialog box:
Click the General tab.
In the Sidebar Theme section, select one of the following options:
Colors that coordinate with the selected Microsoft Office color scheme
Instructs the Sidebar to take colors from the Microsoft Office color scheme that is currently selected in Microsoft Outlook. When you change the Microsoft Office color scheme, the colors of the Coveo Sidebar follow the selected theme (see the Microsoft document Change the Outlook 2010 color scheme).
Predefined color scheme
In the drop-down list, select one of the available Sidebar color presets. With this option, the Sidebar colors are independent from the currently selected Microsoft Office color scheme.
Note: When you are upgrading from an older version of the Coveo Sidebar, an orange shading from the original Sidebar color scheme may remain in the header for all available color schemes.
This is due to the fact that the orange gradient image is still in the Internet Explorer cache.
To eliminate the orange gradient, in the Temporary Internet Files folder on your computer, delete the files for which the name contains outlook.
For Microsoft Windows 7, the typical folder path is: C:\Users\MyUserName\AppData\Local\Microsoft\Windows\Temporary Internet Files
