That's when this software came to the rescue, allowing me to view them without needing to install MS Outlook. It saved me both time and effort.

Recently, my Outlook account stopped responding, so I decided to back up all my data into an OST file. Since I've been using Outlook for a long time, there are numerous files, many of which contain similar emails, making it difficult to manage. In this situation, this software helped me remove duplicates while ensuring that the data remained intact.
