How to Open/Save Offline Folder (OST) on a New Computer without Data Damage?

Use an automated OST to PST conversion tool or the Outlook Import/Export Wizard to convert an OST file to a PST file in Outlook. The wizard uses the 'File' menu to export the OST file, whereas the converter utility uses specialized conversion software to make the process easier.


The Main Distinction Between PST & OST is:

Before starting the transfer procedure, it's critical to understand the main differences between OST and PST (Personal Storage Table) files. To enable offline access and editing of mailbox contents including contacts, calendars, and emails, OST (Offline Storage Table) files are linked to Microsoft Exchange Server, IMAP server, and Microsoft 365. Conversely, Outlook PST files serve as a local database for contacts, emails, and other data and are linked to Microsoft Outlook via the POP3 server.

How Can I Find My OST File and Make a Backup of It?

  • Finding the File (OST): To begin, navigate to the directory containing your OST file. C:\Users\%username%\AppData\Local\Microsoft\Outlook\ is where you can normally find this.

Note: Before making any changes, make sure you have a backup of your OST file. To ensure that there is no inadvertent data loss during the migration, this precautionary step is crucial.

  • Using the Outlook Import/Export Wizard is the first method for migrating an OST file to a PST file in Microsoft Outlook.
