My Outlook PST file has grown too large, and it is starting to affect performance. I am looking for the best tools or methods to reduce the size of my PST file without losing any important emails, attachments, or folders. Can anyone suggest reliable third-party tools or professional methods that actually work well for compressing or splitting PST files? Also, if you have used any of these personally, please share your experience.
