7 Solutions to Fix Outlook Error 500

This error can be a real hindrance, disrupting your workflow and causing unnecessary stress. But fear not! In this guide, we'll explore seven effective methods to help you resolve Outlook Error 500 and get your email client back up and running smoothly.

Understanding the Error

Error 500 typically occurs when there's an issue with the server, either on the user's end or on the server hosting the Outlook service. It can manifest in various ways, such as slow performance, inability to send or receive emails, or outright connection failures.

1. Check Server Status

The first step in troubleshooting Outlook Error 500 is to check the status of the email server. Sometimes, server downtime or maintenance can lead to connectivity issues. Visit the website of your email service provider or check their social media channels for any announcements regarding server status. If the server is down, you may need to wait until it's back up and running.

2. Clear Browser Cache and Cookies

If you're accessing Outlook through a web browser, a buildup of cache and cookies can sometimes cause Error 500. Try clearing your browser's cache and cookies to see if that resolves the issue. Most browsers have a built-in option to clear browsing data. After clearing the cache and cookies, restart your browser and attempt to access Outlook again.

3. Disable Browser Extensions

Browser extensions or add-ons can sometimes interfere with Outlook's functionality and cause Error 500. Temporarily disable all browser extensions and try accessing Outlook again to see if the error persists. If the error disappears after disabling the extensions, re-enable them one by one to identify the culprit. Consider removing or updating any problematic extensions.

4. Restart Outlook

Sometimes, simply restarting Outlook can resolve Error 500. Close the Outlook application or web browser tab and reopen it after a few moments. This will force a fresh connection to the email server and may clear up any temporary glitches causing the error.

5. Update Outlook

Outdated versions of Outlook may contain bugs or compatibility issues that can lead to Error 500. Check for and install any available updates for Outlook to ensure you're running the latest version. In Outlook desktop application, go to File > Office Account > Update Options > Update Now. For web-based Outlook, updates are typically applied automatically.

6. Use Outlook in Safe Mode

Running Outlook in Safe Mode can help diagnose and troubleshoot issues by temporarily disabling add-ins and customizations. To open Outlook in Safe Mode, hold down the Ctrl key and double-click the Outlook shortcut. You'll be prompted to confirm if you want to start Outlook in Safe Mode. If Outlook opens without Error 500 in Safe Mode, the issue may be related to an add-in or customization.

7. Contact Support

If none of the above solutions resolve Outlook Error 500, it may indicate a more complex issue that requires assistance from your email service provider or IT support team. Contact your email provider's customer support for personalized assistance and guidance in resolving the error. Provide them with as much detail as possible about the error and any troubleshooting steps you've already taken.


Outlook Error 500 can be a frustrating roadblock, but with the right approach, it's entirely manageable. By following the steps outlined in this guide, you can effectively troubleshoot and resolve the error, getting your email client back to optimal performance. Remember to always keep your Outlook application or web browser up to date and to seek professional help if needed. With patience and perseverance, you can conquer Outlook Error 500 and regain access to your emails and calendar without hassle.
