I am currently dealing with a very large PST file in Outlook, and it is taking up a lot of disk space on my system. Because of this, Outlook has also started running slower than usual. I have already deleted some old emails and attachments, but the PST file size has not reduced much. I have heard that compressing or compacting PST files can help free up space, but I am not sure which method is the most effective and safe. Can anyone suggest the best ways to compress a PST file and save disk space?
