How Do I Access an OST File?

Do you have an OST file and want to open or read its contents? Then read this guide to know the process to access an OST file manually and using OST to PST Converter.

OST files are not meant to be opened directly by Outlook like PST files. They are linked with a specific Outlook profile and server. So, if you try to open it directly or on another system, you will get errors. To access the data inside the OST file, converting it to PST is the most reliable solution.

Microsoft Outlook is one of the most widely used email clients as it allows for sending and receiving emails for both personal and professional purposes. It stores data in OST and PST files. OST files store emails, contacts, tasks, journals, calendar, and other mailbox items and allow offline access. However, Outlook does not allow opening orphaned or dismounted OST files directly.

Reasons to Access an OST File

• You may need to access an OST file when Outlook is not working, or when you've moved to a new system.
• Accessing an OST file helps recover data from an inactive Outlook profile or an Exchange Server that’s no longer available.
• Opening an OST file allows you to view and extract emails, contacts, calendars, and attachments stored offline.
