Outlook was not even opening correctly since my Outlook PST file had grown so big. I attempted a few manual techniques, but they weren’t particularly effective. The DataVare Outlook PST Compact Expert Tool was then recommended. I was able to quickly reduce the size of my enormous PST file using this program without losing any emails or data. The procedure was quite easy, and I got the results right away. This application is possibly worth attempting if someone is having trouble with Outlook freezing or being slow because of a huge PST file.
