I am using Outlook 2019, and my PST file has become too large, causing Outlook to run slowly and sometimes even freeze. I know that the PST file has a size limit, and I am worried it might get corrupted if it grows any bigger. Can someone please guide me on the safest way to reduce or shrink the PST file size without losing any important emails or data? I have already deleted a few old messages, but the file size has not decreased much. Are there any options in Outlook 2019 to compact the PST file, or do I need to use any third-party tools for this?
