ToolsGround OST to PST Converter is an independent solution for extracting mailbox data from damaged or inaccessible OST files and converting it into a fully usable PST format. Outlook crash, an unexpected shutdown, failure of synchronizing data or issues with the Exchange Server can all cause an OST file to become corrupt. This utility will perform a complete scan of the damaged OST file and accurately restore email messages, attachments, folders, contact lists & all other components of their mailbox. It ensures that the original folder hierarchy and email properties remain unchanged after conversion. It works smoothly without requiring a live Exchange connection or Outlook profile. Even large or severely damaged OST files are processed efficiently, making it suitable for all users. With its clean interface and guided steps, users can complete the extraction process smoothly without technical expertise. The free demo version allows previewing recovered mailbox data before exporting.
