    • DAPI.dll 5.5.2653.23
    • MAPI32.dll 6.5.6944.0
    • EXCHMEM.dll 6.5.6944.0

  • For Exchange 2000/2003 to Exchange 2007 migrations, you can migrate with both Exchange 2003 and Exchange 2007 tools installed on the same machine. In this case you will have the additional dlls noted above. However, the dlls noted below should be the only ones utilized during the migration:
    • MAPI32.dll 1.0.2536.0
    • EXCHMEM.dll 8.0.685.24 (RTM)
    • EXCHMEM.dll 8.1.240.3 (SP1)

By default these DLLs are installed in some or all of the locations specified below. For best results, ensure you have matching DLL versions in the following locations:

    • \Exchsrvr\bin (this only applies to consoles migrating to Exchange 2000 or later)
    • %SystemRoot%\System32
      • WARNING - DO NOT copy CDOEXM.dll to this directory if migrating to Exchange 2003 as it may cause issues with CDOEXM functionality.
    • \Program Files\Microsoft Integration\Microsoft Exchange 2000 (this only applies to consoles with Exchange 2000 System Manager) 
    • \Program Files\Microsoft Integration\Microsoft Exchange (this only applies to consoles with Exchange 2003 System Manager)
    • \Program Files\Microsoft\Exchange Server\bin (this only applies to consoles with Exchange 2007 Management Console)

If you find that the versions do not match in all of these locations, rename the incorrect version to .bak and copy the correct version.
