According to industry reports, more than 70% of organizations must retain business email data for regulatory purposes. This is why many companies use a professional OST to PST Converter from SysInspire Software to make email records accessible and audit-ready.
What Is an OST File?
OST stands for Offline Storage Table. Microsoft Outlook creates this file when connected to Exchange, IMAP, or Microsoft 365 accounts.
It Stores:
Emails
Attachments
Contacts
Calendar items
Tasks
OST files are useful for offline access, but they are not ideal for audits because they are linked to the original mailbox.
Why PST Format Is Better for Compliance Audits
PST stands for Personal Storage Table. It is a portable Outlook data file.
Benefits of PST:
Easy to open in Outlook
Simple to move and archive
Suitable for long-term storage
Helpful for searching records
Easy to share with authorized reviewers
This makes PST a practical format for audit preparation.
