Adds a message service to the current profile and returns that newly added service UID.
The IMsgServiceAdmin2::CreateMsgServiceEx method adds a message service to the current profile. CreateMsgServiceEx calls the message service's entry point function to perform any service-specific configuration tasks. If the SERVICE_UI_ALLOWED flag is set in the ulFlags parameter, the message service being installed can display a property sheet enabling the user to configure its settings.
The MapiSvc.inf file contains the list of providers that make up a message service and the properties for each. CreateMsgServiceEx first creates a new profile section for the message service and then copies all of the information for that service from the MapiSvc.inf file into the profile, creating new sections for each provider.
After all the information has been copied from MapiSvc.inf, the message service's entry point function, MSGSERVICEENTRY, is called with the MSG_SERVICE_CREATE value set in the ulContext parameter. If the SERVICE_UI_ALLOWED flag is set in the CreateMsgServiceEx method's ulFlags parameter, the values in the ulUIParam and ulFlags parameters are also passed when the message service's entry point function is called. Service providers should display their configuration property sheets so users can configure the message service.
If the CreateMsgServiceExlpuidService argument is not NULL, the PR_SERVICE_UID (PidTagServiceUid) property of the message service that was added to the profile is returned in the GUID to which it points.
Pass the value of the PR_SERVICE_UID property in the lpuidService parameter to the IMsgServiceAdmin::ConfigureMsgService method to configure the service.
The Microsoft Outlook 2010 implementation of the MAPI subsystem does not support MAPI_UNICODE and will fail if it is used.
The IMsgServiceAdmin2 interface is exposed by the same object that implements the IMsgServiceAdmin interface, and has been available using Outlook's implementation of the MAPI subsystem since Outlook 2003. Its IID is defined as follows:
#if !defined(INITGUID) || defined(USES_IID_IMsgServiceAdmin2)
DEFINE_OLEGUID(IID_IMsgServiceAdmin2,0x00020387, 0, 0);
The ulFlags SERVICE_NO_RESTART_WARNING might not be defined in the downloadable header file you currently have, in which case you can add it to your code using the following value:
#define SERVICE_NO_RESTART_WARNING 0x00000080
