Converting Microsoft Outlook Messages to TIFF for Delphi

////////////////////////////////////////////////////////////////////////////////////////////////////
// This example was designed for using in Delphi 7 or higher.
//
// 1. Microsoft Outlook 2000 or above should be installed and activated on your PC.
//    Microsoft Outlook Express does not have COM interface and cannot be used as COM-server!
//
// 2. Universal Document Converter 5.2 or above should be installed, too.
//
// 3. Add "Universal Document Converter Type Library" and "Microsoft Outlook XX.0 Object Library" type libraries to the project.
//    XX is the Microsoft Office version installed on your computer.
//
//    Delphi 7:
//      Use the Project | Import Type Library menu.
//    Delphi 2006 or latter:
//      Use the Component | Import Component menu.
//
//    Clear the "Generate Component Wrapper" checkbox and click the "Create Unit" button (Delphi 7) or
//    select the "Create Unit" option (Delphi 2006 or latter).
//
// 4. Notice that the number of Microsoft Outlook's method parameters may depend on the Office version.
