Microsoft Outlook users are well aware about OST file and PST file. Sometimes OST files can become inaccessible due to corruption, profile deletion, Exchange server issues, or system migration. Since Outlook cannot directly import an OST file, the safest way to restore emails, contacts, calendars, and other mailbox items is to convert OST to PST. That’s why, here I have mentioned best and reliable manual method as well as professional methods to convert OST file to PST file in Outlook using EmailsGuru OST to PST Converter .
What Is an OST File?
An OST (Offline Storage Table) file is created when Outlook is connected to Microsoft Exchange Server, Office 365, or an IMAP email account. It stores a synchronized offline copy of your mailbox, allowing you to access emails even when there is no internet connection.
However, OST files depend on the original Outlook profile and mail server. If the profile is deleted, the Exchange account becomes unavailable, or the system crashes, accessing the OST file may become difficult.
What Is a PST File?
A PST (Personal Storage Table) file is Outlook’s portable data file used for storing emails, contacts, calendars, journals, notes, and tasks. Unlike OST files, PST files can be easily imported into Outlook on another computer or profile, making them ideal for backups and migrations.
Why Convert OST to PST?
Data Recovery: OST files are offline copies linked to your Exchange Server account. If the server fails or the account gets corrupted, converting OST to PST helps recover your emails.
Access Offline Data: PST files are standalone and can be accessed without connecting to the Exchange Server.
Migration & Backup: Easily migrate emails to a new system or create backups for safety.
How to Convert OST File to PST File into Outlook?
Manual Method
If your OST file is connected to an active Outlook profile and the mailbox is accessible, you can use Outlook’s built-in Import/Export feature to create a PST file. This method is suitable for users who want to back up their mailbox or transfer data without using third-party software.
Steps to Convert OST to PST Manually

Limitations of the Manual Method
Although Outlook’s built-in export feature is convenient, it has several limitations:
