Microsoft Outlook is most commonly used in managing emails, calendars, and contacts. However, like any other software, this too has its limitations. One of the more troublesome issues Outlook users often face is the “Outlook OST Cannot Be Opened” error. This error usually leaves users inaccessible to crucial items such as email, contacts, or calendar at the worst moment. This issue is typically caused by a corrupted Offline Storage Table (OST) file, which stores a local copy of your mailbox for offline use. But don’t worry — there are ways to solve the issue, and one of the best methods is converting the OST file to PST.

What is an OST File?

The OST file is used by Microsoft Outlook to store a local copy of your mailbox when you are working offline. When you are online, it syncs with your Exchange server. However, this file can become corrupted due to various reasons like unexpected shutdowns, hardware issues, or even malware. If the OST file becomes corrupt, Outlook may display the “OST Cannot Be Opened” error and prevent you from accessing your data.

Why Is This Error There?

There are a few reasons why you may be getting this error:

1. Damaged OST File: The most common reason for this error is a damaged OST file. When your Outlook OST file is corrupted, Microsoft Outlook might not be able to read it properly.

2. Outdated Version of Outlook: At times, using an older version of Outlook can create compatibility issues with the OST file and eventually leads to the error.

3. Corrupt Outlook Profile: Sometimes, even a damaged or misconfiguration outlook profile will stop Outlook from reaching your OST file.

4. PST File Corruption: Sometimes the PST file might get corrupted as it contains all the data.

5. Antivirus Interference: Sometimes, the antivirus software can stop access to the OST file causing this error. How to Convert OST to PST and Fix the Issue

One of the most effective ways to resolve this issue and recover your data is by converting the OST file into a PST file. PST files are much easier to manage and open without the need for an Exchange server.

Let’s walk through the different methods for converting OST to PST.

1. Using Outlook’s Built-In Export Feature

Outlook has a simple export method to save your data into a PST file. If your OST file is not too corrupted, this might work.

Here’s how you can do it:

•Open Microsoft Outlook and go to File.

•Click Open & Export, and then select Import/Export.

•Choose Export to a file, then click Next.

•Select Outlook Data File (.pst) and click Next.
