A common issue for businesses using Microsoft Outlook is the occurrence of corrupted files or folders. This can cause a number of problems, from lost emails and contacts to system instability. It’s important to be able to identify and troubleshoot corrupt Outlook data quickly and effectively in order to avoid extensive downtime and disruption.

In this article, we’ll discuss how to detect and repair corrupted Outlook data as well as provide 13 tips on preventing future issues:

1. Identify the corruption –

The first step in troubleshooting any type of corruption is identifying it. This can be done by checking the application logs within Windows Event Viewer or by running an Office Diagnostics scan (available in most versions of Microsoft Office).

2. Check for Add-Ins –

Corruptions can sometimes be caused by add-ins, so it’s important to check for any conflicting programs or plugins that may be causing issues. To do this, open Outlook and go to File > Options > Add-Ins and look for any suspicious entries.

3. Update Outlook –

Outlook should always be kept up to date with the latest version as older versions are more prone to errors and corruptions. You can check the current version of Outlook you’re running by going to Help > about in the main menu bar.

4. Try Restarting –

Restarting your computer can often help resolve corruptions and other issues with Outlook. It’s best to completely shut down your computer, wait a few minutes and then restart it before trying any other troubleshooting steps.

5. Check System Resources –

If there are too many applications running at once or if the system resources are low, this can cause corruptions in Outlook. Therefore, it’s important to check the amount of available RAM, disk space, and processor power on your computer to make sure everything is within acceptable levels.

6. Run an SFC Scan –

SFC (System File Checker) scans can be used to detect and repair corrupted or missing Windows system files which can sometimes lead to Outlook corruptions. To run an SFC scan, open the Command Prompt as an administrator and enter “sfc /scannow”.

7. Try the Inbox Repair Tool –

The Microsoft Inbox Repair Tool (Scanpst.exe) can be used to scan, diagnose and repair corrupt Outlook data files (.pst or .ost). You can access this tool by going to Start > All Programs > Accessories > System Tools > Scanpst.exe.

8. Run a CHKDSK Scan –

A CHKDSK (Check Disk) scan can be used to detect and fix any errors on your computer’s hard drive that may be causing corruptions in Outlook. To run this scan, open the Command Prompt as an administrator and enter “chkdsk /f”.

9. Repair or Reinstall Office –

If all else fails, you may need to repair or reinstall Microsoft Office in order to fix the corruption. You can access this feature by going to Control Panel > Programs and Features > Microsoft Office > Change/Repair.

10. Backup Regularly –

Regular backups of your Outlook data are essential for quickly recovering from any type of corruption or data loss situation. It’s recommended that you set up scheduled backups at least once a week in order to protect yourself against any unexpected issues.

11. Reduce Mailbox Size –

Outlook corruptions often occur when the mailbox size exceeds 2GB, so it’s important to regularly delete items in order to keep the mailbox size below 2GB. You can find the current size of your mailbox by going to File > Account Settings > Account Settings.

12. Run an Antivirus Scan –

It’s also recommended that you run a full antivirus scan on your computer to ensure that there are no malicious programs or viruses present which may be causing corruptions. To do this, simply open your antivirus software and initiate a complete system scan.

13. Use Microsoft Support –

If you’re still having trouble with Outlook corruption after trying all of the above steps, it’s best to contact Microsoft Support for further assistance as they have access to more advanced tools and resources than most users.


By following the above steps, you can help reduce the risk of Outlook corruptions and ensure that your data is safe and secure. If you’re still having trouble with Outlook corruption after trying all of these steps, then it’s best to contact Microsoft Support for further assistance.
