INFO: Items Required to Use DAPI

ID: Q169551

The information in this article applies to:

Exchange Development Kit (EDK)
Microsoft Exchange Server, versions 4.0, 5.0

SUMMARY

In order to use DAPI on a machine there are several requirements:

The machine that the application is running on must be running NT. The DAPI functions do not run on Windows 95.

The registry also needs to have the following entries under the key


HKEY_CURRENT_USER\SOFTWARE\Microsoft\Exchange\MSExchangeAdminCommon:


      AdminLangID          REG_DWORD      0x409
      ANGAutotextFormat    REG_SZ         %First%1Last
      DNGAutotextFormat    REG_SZ         %First %Last

Finally, there are three DLLs required to run DAPI and are listed below.
```
      Dapi.dll
      Libxds.dll
      Exchmem.dll 
```

All of the registry entries and DLLs are installed by the Exchange Admin program.

If these requirements are not met, you may get an error returned, as described in the following article in the Microsoft Knowledge Base:
