SUMMARY

Certain MAPI configurations may not include entries in the Mapisvc.inf file for Microsoft Exchange services, even though the appropriate MAPI providers for Exchange have been installed. For example, you may install Exchange Administrator on a server to get a MAPI implementation.

MORE INFORMATION

Mapisvc.inf holds entries for the available MAPI services on a particular computer. Installing Exchange Administrator installs a fully functional version of the MAPI subsystem, but does not update Mapisvc.inf. If you want to develop server applications that need to log on to the Exchange message store, Mapisvc.inf must contain the appropriate entries.

To add entries to Mapisvc.inf for the Exchange Message Store service, follow these steps:
  1. In Notepad, create a new text file. Paste the following text in the file, and save the file as Msems.inf:
    [Services]
    MSEMS=Microsoft Exchange Server
    [Default Services]
    MSEMS=Microsoft Exchange Server

    [EMS_Hook]
    PR_DISPLAY_NAME=MS Exchange Hook
    PR_PROVIDER_DISPLAY=MS Exchange Hook
    PR_PROVIDER_DLL_NAME=EMSMDB.DLL
    PR_SERVICE_INSTALL_ID={6485D26A-C2AC-11D1-AD3E-10A0C911C9C0}
    PR_RESOURCE_TYPE=MAPI_HOOK_PROVIDER
    PR_RESOURCE_FLAGS=HOOK_INBOUND
    					
  2. Use Mergeini.exe to merge the Msems.inf file into Mapisvc.inf. Mergeini.exe is a utility that comes with the Microsoft Platform Software Development Kit (SDK). The syntax is as follows:
    mergeini <full path to msems.inf> -m
    					
It is possible to leave out the transport sections from above when modifying your MAPISVC.INF file. This would not affect clients that log in with the MAPI_NO_MAIL flag set, such as NT services. However, transport-related functions (such as EnumAdrTypes and IMAPISession::MessageOptions) will not work properly.
