I am using Outlook for work, and my PST file has become extremely large (around 15–18 GB). Because of this, Outlook has started getting slow, and sometimes it even freezes while sending/receiving emails. I am worried the file might get corrupted if it keeps growing. Can anyone suggest safe methods to manage and compress a large PST file without losing any emails or data? Also, is there any option in Outlook that can help reduce the file size?
