My Outlook PST file has become quite large, and it is starting to slow down Outlook’s performance. I think a lot of the data inside is unnecessary—like deleted items, junk emails, and old attachments. Can anyone suggest an effective way to remove these unwanted files or items from my PST to reduce its overall size without losing important data? I’d really appreciate a detailed solution, or any reliable method or tool recommendation to clean up and compact the PST file safely.
