Microsoft Outlook is a powerful email client used by millions worldwide. However, encountering Error 500 in Outlook can be frustrating, preventing you from accessing your emails. This error usually appears when trying to log in via Outlook Web Access (OWA) and indicates a server-side issue or misconfiguration. In this article, we’ll explore the possible causes and provide practical solutions to resolve the issue efficiently.

What Causes Microsoft Outlook Error 500?

The HTTP 500 Internal Server Error in Outlook occurs when the server encounters an issue and cannot process the request. Some of the common causes include:

• Corrupted Cookies or Cache – Stored browser data interfering with login.
• Outlook Web App (OWA) Issues – Server-side errors affecting web access.
• Misconfigured Account Settings – Problems with Exchange Server settings.
• Authentication Errors – Failed login due to expired or invalid credentials.
• Service Outages – Microsoft server downtime causing temporary disruptions.

How to Fix Outlook Error 500

1. Clear Browser Cache and Cookies

Since corrupt cache or cookies can cause login issues, clearing them is the first step:

• Google Chrome:

  1. Click on the three-dot menu > Settings.
  2. Go to Privacy & Security > Clear Browsing Data.
  3. Select Cached images and files and Cookies > Click Clear data.

• Microsoft Edge:

  1. Click on the three-dot menu > Settings.
  2. Navigate to Privacy, search, and services > Clear browsing data.
  3. Select the relevant options and clear them.

Try logging into Outlook again and see if the error is resolved.

2. Open Outlook in Private/Incognito Mode

Sometimes, browser extensions or cached sessions cause conflicts. Try accessing Outlook using Incognito Mode:

• Google Chrome: Press Ctrl + Shift + N
• Microsoft Edge: Press Ctrl + Shift + N
• Mozilla Firefox: Press Ctrl + Shift + P

If Outlook works in private mode, disable extensions and try logging in normally.

3. Restart Your Browser or Try a Different One

• Close and restart your browser.
• If the issue persists, try using a different browser (Chrome, Edge, or Firefox).

4. Check Microsoft Server Status

Sometimes, the issue is on Microsoft’s end. Check their service status page to see if there are outages:

If there’s an outage, you may have to wait until Microsoft resolves it.

If you’re using Outlook with Microsoft Exchange Server, incorrect configurations can trigger Error 500. Try:

• Removing and re-adding your Exchange account in Outlook.

Some Outlook add-ins may interfere with email access. Disable them as follows:

1. Open Outlook Desktop App.
2. Go to File > Options > Add-ins.
3. Click on Manage COM Add-ins > Go.
4. Uncheck all add-ins and restart Outlook.

1. Open Command Prompt (Run as Administrator).
2. Type:

   ipconfig /flushdns
   ipconfig /release
   ipconfig /renew
   

3. Restart your computer and try accessing Outlook again.
