My Outlook PST file has grown too large, and it is starting to slow down my Outlook performance. I want to reduce the size of the PST file, but I am worried about accidentally losing emails or important data during the process. Can anyone guide me on the safe and effective ways to compress or compact a large PST file? Are there any options in Outlook, or should I use third-party tools?
