How to Decrease an Oversized PST File Without Data Loss?

[Brantanson01]

I am currently facing an issue with my Outlook PST file—it has become oversized and is now affecting performance. I want to reduce the size of this PST file, but without losing any important emails, attachments, or folders. I have already tried basic cleanup, but the file is still too large. Can anyone suggest safe and effective methods to decrease the size of an oversized PST file without risking data loss?
