Managing large PST files can be tricky. One of the safest ways is to use Outlook’s built‑in “Compact Now” (or “Compact Folder”) feature after deleting or archiving unused or old emails. Before doing that, I always recommend backing up the entire PST file just in case.
If that doesn’t shrink the file enough, you might consider using a specialized tool that can archive or split PST data, for example moving old emails into a separate archive PST. That helps reduce size while keeping all data accessible. And finally, regularly archiving old data rather than letting a single PST grow indefinitely is a good habit to prevent performance issues.

This is a useful guide! Compressing and managing PST files carefully is important to prevent Outlook slowdowns and avoid data loss. Archiving old emails, compacting PSTs, and removing unnecessary attachments are practical steps. Using trusted third-party tools can help if the file is very large, but always keeping a backup first is key. Thanks for sharing these techniques!
