  • Advance scanning mode for severely corrupted Exchange OST file. It also recovers permanently deleted email data and this benefits users a lot who have lost crucial data in deletion.
  • Selective data can be exported, using checking/unchecking option and Mail Filters as well. Other advance features like; Split PST, support for orphan, inaccessible, and corrupted OST files are also efficient.

  • No option to work on multiple OST files in batch. The recovery and conversion has to be done on OST files one by one only.

Software is no doubt a professional choice and can be well recommended for enterprise and organizational level. Overall performance of software with dignified accuracy and precision is spellbound and is worth for such a little investment.
