Yes, an OST recovery tool can recover data from large OST files, including files approaching or exceeding the typical 50 GB size limit, depending on the file condition and available system resources. SysInfo OST Recovery Tool is designed to handle corrupt, inaccessible, and damaged Outlook OST files and recover important mailbox items such as emails, attachments, contacts, calendars, tasks, journals, and notes. It provides Standard, Advanced, and Deep recovery modes to address different levels of corruption. The tool can also recover encrypted OST files and save the recovered data in formats including PST, EML, MSG, DBX, and MBOX. For large OST files, ensure sufficient free disk space is available for scanning and saving the recovered data. The software's date-range filter can also help selectively recover required mailbox content instead of processing unnecessary data.
