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:   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 [MSEMS] PR_DISPLAY_NAME=Microsoft Exchange Server Sections=MSEMS_MSMail_Section PR_SERVICE_DLL_NAME=emsui.dll PR_SERVICE_INSTALL_ID={6485D26A-C2AC-11D1-AD3E-10A0C911C9C0} PR_SERVICE_ENTRY_NAME=EMSCfg PR_RESOURCE_FLAGS=SERVICE_SINGLE_COPY WIZARD_ENTRY_NAME=EMSWizardEntry Providers=EMS_DSA, EMS_MDB_public, EMS_MDB_private, EMS_RXP, EMS_MSX, EMS_Hook PR_SERVICE_SUPPORT_FILES=emsui.dll,emsabp.dll,emsmdb.dll [EMS_MDB_public] PR_RESOURCE_TYPE=MAPI_STORE_PROVIDER PR_PROVIDER_DLL_NAME=EMSMDB.DLL PR_SERVICE_INSTALL_ID={6485D26A-C2AC-11D1-AD3E-10A0C911C9C0} PR_RESOURCE_FLAGS=STATUS_NO_DEFAULT_STORE 66090003=06000000 660A0003=03000000 34140102=78b2fa70aff711cd9bc800aa002fc45a PR_DISPLAY_NAME=Public Folders PR_PROVIDER_DISPLAY=Microsoft Exchange Message Store [EMS_MDB_private] PR_PROVIDER_DLL_NAME=EMSMDB.DLL PR_SERVICE_INSTALL_ID={6485D26A-C2AC-11D1-AD3E-10A0C911C9C0} PR_RESOURCE_TYPE=MAPI_STORE_PROVIDER PR_RESOURCE_FLAGS=STATUS_PRIMARY_IDENTITY|STATUS_DEFAULT_STORE|STATUS_PRIMARY_STORE 66090003=0C000000 660A0003=01000000 34140102=5494A1C0297F101BA58708002B2A2517 PR_DISPLAY_NAME=Private Folders PR_PROVIDER_DISPLAY=Microsoft Exchange Message Store [EMS_DSA] PR_DISPLAY_NAME=Microsoft Exchange Directory Service PR_PROVIDER_DISPLAY=Microsoft Exchange Directory Service PR_PROVIDER_DLL_NAME=EMSABP.DLL PR_SERVICE_INSTALL_ID={6485D26A-C2AC-11D1-AD3E-10A0C911C9C0} PR_RESOURCE_TYPE=MAPI_AB_PROVIDER [MSEMS_MSMail_Section] UID=13DBB0C8AA05101A9BB000AA002FC45A 66000003=01050000 66010003=04000000 66050003=03000000 66040003=02000000 [EMS_RXP] PR_DISPLAY_NAME=Microsoft Exchange Remote Transport PR_PROVIDER_DISPLAY=Microsoft Exchange Remote Transport PR_PROVIDER_DLL_NAME=EMSUI.DLL PR_SERVICE_INSTALL_ID={6485D26A-C2AC-11D1-AD3E-10A0C911C9C0} PR_RESOURCE_TYPE=MAPI_TRANSPORT_PROVIDER 66090003=40000000 660A0003=0A000000 [EMS_MSX] PR_DISPLAY_NAME=Microsoft Exchange Transport PR_PROVIDER_DISPLAY=Microsoft Exchange Transport PR_PROVIDER_DLL_NAME=EMSMDB.DLL PR_SERVICE_INSTALL_ID={6485D26A-C2AC-11D1-AD3E-10A0C911C9C0} PR_RESOURCE_TYPE=MAPI_TRANSPORT_PROVIDER 66090003=00000000 [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   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  -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.
