How to Recover and Convert Corrupted OST to PST

Microsoft Outlook is one of the most widely used email clients for both business and personal communication. It stores your mailbox data in two primary file formats: OST  and PST. While the OST file enables users to work offline and synchronize their changes with the Exchange Server or Microsoft 365, it can get corrupted for various reasons. A damaged OST file can make essential emails, contacts, calendars, tasks, and attachments inaccessible.

Fortunately, there are reliable ways to recover corrupted OST files and convert them into PST format so that you can access mailbox data through Microsoft Outlook easily. In this blog, you will find the causes of OST file corruption, manual recovery methods, and the fastest way to convert OST to PST.

Why Does OST File Corruption Happen?

An OST file can turn inaccessible or corrupted due to the following reasons:

• Abrupt system shutdown or power failure
• Outlook crashing while the OST file is in use
• Damaged bad sectors on the hard disk or storage device

Virus and malware attacks

• Synchronization issues between the OST file and Exchange Server or Microsoft 365

Oversized OST files

•  Corruption in the Outlook profile

 Improper termination of Outlook

When the OST file gets corrupted, you might experience problems like synchronization errors, missing emails, the freezing of Microsoft Outlook, or you will be unable to open your mailbox.

What Are the Signs of a Corrupted OST File?

Here are a few common symptoms of OST file corruption:

•  Outlook does not start up

Repetitive synchronization errors

• Missing emails or other mailbox folders

Unexpected crashes in Microsoft Outlook

• Error messages while accessing mailbox items

Sluggish performance of Outlook

• Failure to synchronize mailbox with Exchange Server

If these symptoms are present, OST file recovery is a priority.

Manual Methods to Recover Corrupted OST Files

You can try to recover corrupted OST files using some manual methods before resorting to a third-party tool:

Method 1: Restart Outlook

Sometimes, a temporary synchronization issue might cause Outlook to misbehave. Restart Outlook and check if the issue is resolved.

Method 2: Create a New Outlook Profile

A corrupted Outlook profile may be the culprit behind the OST file not functioning correctly.

Follow these steps:

1. Navigate to Control Panel.

2. Click on Mail.

3. Click on Show Profiles.

4. Create a new profile for Outlook and configure your Exchange or Microsoft 365 account.

5. Let Outlook rebuild the OST file.

This method will only be beneficial if your mailbox is still available on the mail server.

 Method 3: Rebuild the OST File

If your mailbox is accessible on Exchange Server or Office 365, you can attempt to rebuild the OST file.

1. Close Microsoft Outlook.

2. Locate the OST file.

3. Rename or delete it.

4. Restart Outlook.

Outlook will automatically create a new OST file for you after synchronizing all the mailbox data.

Limitation: This method will only work if the mailbox exists on the server and cannot recover an orphaned OST file.

Why Should You Convert Corrupted OST to PST?

Converting a corrupted OST file to PST format offers several advantages:

• You can easily access the mailbox items without the need for Exchange Server or Microsoft 365.
• Emails can be opened in Microsoft Outlook at any time.
• Essential mailbox items can be archived.
• Data can be migrated to another Outlook profile.
• It acts as a backup of your mailbox data.
• You can recover data from orphaned OST files.

When manual methods fail to recover the OST file, converting it into a PST file becomes the most reliable option.
