![]() To handle messages in an initialization thread, a MAPI client that is implemented as a service does the following:Ĭalls the MsgWaitForMultipleObjects function when the main thread blocks.Ĭalls the GetMessage, TranslateMessage, and DispatchMessage sequence of Windows functions to handle the message when MsgWaitForMultipleObjects returns the sum of the value of the nCount parameter and the value of WAIT_OBJECT_0, which indicates that a message is in the queue. Other types of clients do not have to set a flag for logon because it is automatically set by MAPI. They must set the MAPI_NO_MAIL flag in the call to MAPILogonEx. MAPI clients that are written as Windows services and written with the MAPI client interface have an additional requirement. Clients that are services must set a special flag, MAPI_NT_SERVICE, in the ulFlags member of the MAPIINIT_0 structure that is passed to MAPIInitialize and in the ulFlags parameter that is passed to the MAPILogonEx function to inform MAPI of their special implementation. Both MAPIInitialize and OleInitialize make calls to the CoInitialize function to initialize the Component Object Model (COM) libraries. A call to the OleInitialize function is also necessary to use the OLE libraries. In Exchange 2016 and Exchange 2019, MAPI over HTTP can be applied across your entire organization, or at the individual mailbox level. ![]() Because of identity and security issues between client applications and the MAPI spooler, most transport providers are not supported in a service.Īll MAPI client applications, whether they are implemented as Windows services, must call the MAPIInitialize function to initialize the MAPI libraries. Outlook clients that are not MAPI over HTTP capable can still use Outlook Anywhere (RPC over HTTP) to access Exchange through a MAPI-enabled Client Access server. In addition, MAPI clients can send and receive messages by using only the Microsoft Exchange Server or another server-based transport provider. They can send messages only through a tightly coupled message store and transport provider. MAPI clients have the following limitations: To enable MAPI client applications that are written as Windows services to operate with MAPI-compliant service providers, MAPI imposes several limitations and requirements.
