    *  Error  YYYY/MM/DD hh:mm CExBackup::backupFile:HrESEBackupOpenFile: Error Number 0xc7ff07e0: (null)
  3. Cause:
    4. The issue was caused by an older ESEbcli2 DLL file (esebcli2.dll) file found in the directory:

           ${System-Root}\system32 

           compared to 

           ${Exchange-Install-Home}\Exchsrv\bin

    Notes:
    For example, the version of the ESEbcli2 DLL file (esebcli2.dll) in the ${Exchange-Install-Home}\Exchsrv\bin directory was 6.5.7226.0, whereas the version in ${System-Root}\system32 was 6.0.4712.0.
  4. Resolution:
    5. To resolve the issue, please:

    1. Make a copy of the ${System-Root}\system32\esebcli2.dll file (for backup purpose)
    2. Copy the ESEbcli2 DLL file from: 

      ${Exchange-Install-Home}\Exchsrv\bin\esebcli2.dll 

      into 

      ${System-Root}\system32\
