How to Convert Outlook OST to PST File Free?

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

1. Open Microsoft Outlook on your computer.
2. Click the File tab in the upper-left corner.
3. Select Open & Export and then click Import/Export.
4. In the Import and Export Wizard, choose Export to a file and click Next.
5. Select Outlook Data File (.pst) and click Next.
6. Choose the mailbox or folder you want to export. To include all subfolders, check the Include subfolders option.
7. Click Next, then select the location where you want to save the PST file.
8. Choose how Outlook should handle duplicate items if prompted.
9. Click Finish to begin the export process.
10. If desired, set a password for the PST file or leave it blank and click OK.

Note: Once the export is complete, the PST file will be saved to your selected location and can be opened in Outlook using File > Open & Export > Open Outlook Data File.

Limitations of the Manual Method

Although Outlook's built-in export feature is convenient, it has several limitations:

• It only works if the OST file is connected to an active Outlook profile.
• It cannot convert orphaned, inaccessible, or damaged OST files.
• The original Exchange Server, Microsoft 365, or IMAP account must still be available.
• Exporting large mailboxes can take considerable time.
