How to Fix Microsoft Edge Not Working

Are you experiencing issues with Microsoft Edge not working? If so, this guide will help you troubleshoot and resolve the problem.

To start, sign in to your Office 365 or Microsoft 365 admin portal and verify that your license is valid. This step may seem simple, but it's crucial in resolving sync issues.

When troubleshooting a sync issue, follow these steps:

1. Check edge://sync-internals under Credentials for any error messages. In this case, the error message we're looking at is Last Token Error, EDGE_AUTH_ERROR: 3, 54, 3ea.

2. Before you begin troubleshooting, take a look at the Common sync issues to see if your problem matches one of these common issues.

It's essential to understand the difference between identity and sync issues before proceeding with troubleshooting. An identity error refers to an issue with a user's account, whereas a sync issue is related to data syncing between devices or accounts.

Before treating an issue as a sync issue, ensure that the user is signed in to the browser with a valid account. This is often where identity issues are confused with sync issues.

A key use case for maintaining user identity in the browser is to support sync functionality. Therefore, it's crucial to understand the difference between these two types of issues before attempting to troubleshoot.

Before you begin troubleshooting sync issues, take a moment to review the differences between identity and sync issues:
