Understanding the Microsoft Teams Login Loop

What is a Microsoft Teams Login Loop?

A Microsoft Teams login loop occurs when users attempt to sign in to their Teams account, only to find themselves repeatedly redirected back to the login page without successfully accessing the platform. This issue can manifest in various ways:

• Endless redirects between the login page and the Teams interface
• Stuck on the “Checking your credentials” screen
• Continuously prompted to “Pick an account” without progressing
• Browser constantly refreshing the login page

This problem can affect the Microsoft Teams web client, desktop application, and even mobile apps across different platforms.

Common Causes of Login Loops

Several factors can contribute to the Microsoft Teams login loop:

1. Browser cookie and cache issues
2. Outdated browser versions
3. Incorrect browser settings
4. Network connectivity problems
5. Account authentication issues
6. Conflicts with other Microsoft 365 services

Understanding these root causes is crucial for implementing effective solutions. Let’s explore each in detail and learn how to address them.

Advanced Troubleshooting for Microsoft Teams Login Issues

If the browser-specific fixes don’t resolve your login loop, try these advanced troubleshooting steps:

1. Clear Microsoft Teams Cache

Clearing the Teams cache can often resolve persistent login issues:

• On Windows:
  1. Close Teams completely

Ensure your network connection is stable and that you can access other Microsoft services:

• Test your internet connection speed
• Try accessing other Microsoft 365 services like Outlook or SharePoint
• If on a corporate network, contact your IT department to check for any firewall or proxy issues

3. Verify Account Credentials

Double-check that you’re using the correct account credentials:

• Ensure you’re not mixing personal and work accounts
