What is a PST File?
A PST file is Outlook’s storage bin for your life—emails, attachments, calendars, contacts, tasks, notes, the works. When you’re not on Exchange or IMAP, it’s where everything lives. But when it corrupts, you’re screwed. You lose access to critical stuff, and if you’re in business, that means lost deals, missed deadlines, and pissed-off clients. A small firm lost a $10,000 contract because their PST crapped out. That’s why knowing how to Repair a corrupt PST File Using Stellar Repair for Outlook is non-negotiable—it’s not just a file; it’s your digital brain.
Why Do PST Files Become Corrupt?

- Size Overload: Old PSTs cap at 2GB, new ones at 50GB. Push it, and it blows up. A user lost three months of emails hitting 55GB.
- Crashes: Power outage or Outlook freezing mid-save? Boom, corruption. A pro lost a week’s work this way.
- Malware Attacks: Viruses love PSTs. One hacker encrypted a company’s file, demanding $5,000 in ransom.
- Disk Issues: Bad hard drive sectors nuke data. A laptop failure wiped a freelancer’s contacts.
