Customizing the Help Menu
Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.
To add your own link to the Office Communicator Help menu, add the HelpMenuText and HelpMenuURL registry keys to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Communicator. This policy can also be set in either HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER, but settings in HKEY_LOCAL_MACHINE take precedence.
For example, setting the HelpMenuURL registry key to a valid network address and the HelpMenuText key to "Contoso Help Desk" adds the Office Communicator Help menu to both the main window and the Conversation window.
