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.

If your Outlook PST file has become too large and Outlook is running slowly or hanging, the best way is to reduce the size of the PST by removing unnecessary emails, attachments, and folders. I recently used Softaken Compress PST Software, and it is a really amazing tool. This software reduces the size of the PST file in a few minutes without any data loss. It also has the facility to manage emails, attachments, and other unnecessary items. Best of all, Outlook's performance improves immediately. If you are also troubled by a large PST file, then definitely try the Compress PST Tool once. It is a user-friendly, safe, and reliable solution.
