How to Fix Outlook Error 500

Now that we’ve discussed the possible causes, let’s dive into the solutions to fix Outlook Error 500.

1. Clear Your Browser’s Cache and Cookies

One of the simplest yet effective solutions is to clear your browser’s cache and cookies. Accumulated data can sometimes interfere with the way your browser interacts with Outlook, causing the error. Here’s how you can clear cache and cookies on popular browsers:

Google Chrome:

  1. Click on the three dots at the top-right corner of the browser.
  2. Go to “More tools” > “Clear browsing data.”
  3. Select “Cookies and other site data” and “Cached images and files,” then click “Clear data.”

Mozilla Firefox:

  1. Click on the hamburger menu at the top-right corner of the browser.
  2. Go to “Options” > “Privacy & Security.”
  3. Under “Cookies and Site Data,” click “Clear Data.”

Repeat this process for any other browser you use to access Outlook.

2. Update Your Outlook Version

An outdated version of Outlook may be incompatible with the latest server configurations, leading to Error 500. To resolve this, update your Outlook to the latest version:

  1. Open Outlook and click on “File” > “Office Account.”
  2. Click “Update Options” > “Update Now.”

3. Check Your Login Details

Ensure you’re using the correct login details. If you’ve recently changed your password or account information, you may have forgotten to update the information in Outlook. If you’re unsure, try resetting your password and logging in again.

4. Use Outlook Diagnostic Tool

If you’re using the desktop version of Outlook, you can use the Microsoft Support and Recovery Assistant tool to diagnose and resolve the error:

  1. Download and install the Microsoft Support and Recovery Assistant.
  2. Open the tool and select “Outlook” > “Next.”
  3. Follow the prompts to diagnose and resolve the issue.

5. Contact Your Server Administrator

If none of the above solutions work, the issue might be server-side, especially if the “Mailbox Not Found” message appears. Contact your server administrator or email service provider to check if there are any ongoing server issues or if there’s a problem with your mailbox.
