What Is an OST File?
OST stands for Offline Storage Table. Microsoft Outlook automatically creates OST files when users configure Outlook with:
- Microsoft Exchange Server
- Microsoft 365 or IMAP mail accounts
These files provide a synchronised offline copy of mailbox data, so that users can access their email, contacts, tasks, calendars, journals,, and attachments even when offline.
However, OST files are directly linked to the Outlook profile and Exchange account that created them. If the connection breaks, the OST file may become inaccessible or orphaned.
Common Reasons for OST Corruption and Inaccessibility:
- Exchange Server goes down
- Outlook sync problems
- Mailbox deleted accidentally
- Outlook profile corruption
- Hard drive failures
- Virus/malware attacks
- System failure
- Reinstallation of Outlook
- Change password
- Moving to another device
As the Outlook application does not allow the direct opening of orphaned OST files, users generally need a professional OST to PST converter program.
Why Convert OST to PST?
PST (Personal Storage Table) files are portable Outlook data files that can be easily imported into multiple Outlook profiles or systems.
Advantages of OST to PST Conversion are:
Basic Mailbox Backup
PST files can be stored externally for long-term backup and archiving.
Outlook migrations
Users can move mailbox data from one machine to another without Exchange Server requirements.
Recover Inaccessible Mailboxes
Mailbox data is available after PST conversion even if the Exchange Server is not online.
Legal and Regulatory Requirements
Organisations typically archive emails to PST or PDF format for audit and regulatory compliance purposes.
Orphaned OST files Access
Users can retrieve data from deleted or inaccessible Outlook accounts.
