OutlookExtension.h

The file OutlookExtension.h defines the two client extension classes required by Microsoft Outlook. These classes, CMessageEvents and CClientExtension, provide the messaging interface used to extend the Outlook client. The CClientExtension class is strictly formatted to Outlook interface standards. The CMessageEvents class contains both Outlook interface standards and application-specific logic. OutlookExtension.h also contains the file logging definitions used by LogContent.
