Message Service Implementation
Applies to: Outlook 2013 | Outlook 2016
A message service is one or more related service providers grouped together for the purpose of simplifying installation and configuration. All service providers should be included in a message service.
To implement a message service with one or more providers, use the following procedure:
Design the message service, determining the number and type of service providers to be included. For more information about how to design a message service, see Designing a Message Service.
Create a setup program to install the service providers in the message service. For more information about writing a message service setup program, see Supporting Message Service Installation.
Create an entry point function to perform configuration. For more information about writing a message service entry point function, see Supporting Message Service Configuration and MSGSERVICEENTRY.
Create a public header file that contains the property tags and descriptions of valid values for any custom properties that the message service supports.
