Introduction
Microsoft Outlook is a widely used email client that helps millions of people communicate and manage their emails efficiently. However, it can be frustrating when the application suddenly stops working, leaving users unable to access their emails and causing disruptions to their workflow. In this article, we will explore common reasons why Microsoft Outlook may stop working and provide step-by-step solutions to troubleshoot and fix the issue.
What Causes Microsoft Outlook to Stop Working?
- Corrupt PST or OST Files
One of the most common reasons for Outlook to stop working is corrupt PST (Personal Storage Table) or OST (Offline Storage Table) files. These files store all your mailbox data, and any corruption can lead to malfunctioning of Outlook.
- Third-Party Add-ins Conflict
Third-party add-ins can enhance Outlook’s functionality, but they can also cause conflicts, leading to unexpected crashes or errors. Conflicting add-ins can disrupt the application’s performance.
- Outdated or Faulty Plugins
Outdated or faulty plugins can hamper Outlook’s smooth operation. It’s essential to keep all plugins up-to-date and ensure they are compatible with your Outlook version.
- Overloaded Outlook Profile
A large number of emails, contacts, and calendar items in your Outlook profile can lead to overload and affect the application’s performance.
- Antivirus or Firewall Interference
Sometimes, antivirus or firewall settings may mistake Outlook functions as suspicious and block them, causing the application to stop working.
Troubleshooting Microsoft Outlook Issues
- Check Internet Connectivity
Before jumping to conclusions, verify your internet connection. Outlook requires an active internet connection to function correctly.
- Restart Microsoft Outlook
A simple restart can resolve many temporary glitches and restore Outlook to normal functionality.
- Run Outlook in Safe Mode
Running Outlook in Safe Mode disables all add-ins and helps identify if any third-party add-ins were causing the issue.
- Disable Add-ins
If you suspect add-ins are causing the problem, disable them one by one to find the culprit.
- Repair Outlook Data Files
Use the built-in Inbox Repair Tool (scanpst.exe) to repair corrupted PST or OST files.

Keeping your Outlook and Windows updated ensures you have the latest bug fixes and improvements.
