My Outlook PST file has become quite large and is starting to slow down my system. I have heard that using Outlook’s Archive feature can help reduce the PST file size, but I am not exactly sure how to use it properly. Can someone please explain step-by-step how to archive old emails or data in Outlook to shrink the PST file size? Also, does archiving automatically compress the PST file, or do I need to do something else after that to free up space? Any clear instructions or additional tips to optimize PST file size would be really helpful.
