Understand OST File in Brief

An Offline Storage Table (OST) file is a local copy of your mailbox data on an Exchange Server. When you’re working with Microsoft Outlook in offline mode, it’s the OST file that lets you access your emails, calendar entries, contacts and more. This file allows you to work even when there is no internet connectivity, syncing all changes with the server once you’re back online.

However, a malicious OST file can wreak havoc on your productivity. It may prevent you from accessing essential data or worse yet, lead to data loss. Recognizing the potential threats posed by a corrupted OST file, we delve into recovery methods next that ensure data safety and continuity of operations.

Manual Methods to Recover a Malicious OST File

OST Files (Offline Storage Tables) are critical components of Outlook, storing all your mail data. When these files become malicious or corrupt, they put all this data at risk. But don’t panic! There are manual methods to recover your malicious OST file.

Method 1: Using the ScanOST.exe Tool

The first option involves using the built-in tool in Microsoft Outlook – ScanOST.exe . This tool was designed specifically to detect and repair errors in your OST file. Here’s how you can use it:

• Close Outlook if it’s open.
• Locate the ScanOST.exe executable file. It’s typically located in the ‘Microsoft Office’ directory.
• Double-click on the ScanOST.exe file to launch it.
• In the tool, select the OST file you wish to recover.
• Choose either ‘Scan and Repair’ or ‘Scan only’. The former will automatically fix any detected issues.
• Click on ‘Begin Scan’.

While easy to use and free, ScanOST.exe has its limitations:

• It’s not available in Outlook 2010 and later versions.
• It might not be effective for severe corruption cases.
• It cannot recover deleted items.

Despite these drawbacks, it’s still a viable first step for users seeking to recover a malicious OST file.

Method 2: Export and Import Method

Another approach is the export and import method. This involves exporting your data to a new PST file then importing this data back into Outlook. Here are the steps:

• Open Outlook and go to “File > Options > Advanced”.
• Click on ‘Export‘ under the ‘Export’ section.
• Select ‘Export to a file‘.
• Choose ‘Outlook Data File (.pst)’.
• Select the mailbox or folders you want to export then click ‘Next’.
• Choose a location to save your new PST file and click ‘Finish’.

The advantages of this method are:

• It creates a backup of your data.
• You can transfer data from one computer to another.

However, there are some disadvantages:

• It can be time-consuming for large mailboxes.
• Some items may not be exported such as contact groups.

These manual methods provide viable options for users looking to recover their malicious OST files. Remember, it’s important to regularly backup your data as part of your recovery strategy!
