Required Functionality for Transport Providers

Every MAPI transport provider must:

• Follow the general guidelines for working with MAPI and other service providers as described in MAPI Programming Basics and Service Provider Basics.
• Have its transport provider DLL expose to MAPI its XPProviderInit initialization function.
• Expose to MAPI its implementation of the IXPProvider and IXPLogon interfaces.
• Expose to MAPI and client applications its implementation of the IMAPIStatus interface. For information about implementing IMAPIStatus, see Implementing a Status Object.
• Implement a property sheet dialog box for configuration. For information about implementing property sheets, see Implementing a Property Sheet.
