How to fix outlook.office.com sign in failed error 500 Something went wrong. Repeating redirects detected

If you use Outlook on the web, you may have encountered an error message that says “500 Something went wrong. Repeating redirects detected.” This error prevents you from accessing your email account and can be very frustrating. In this article, we will explain what causes this error and how to fix it.

What Causes Outlook Error 500?

Outlook Error 500 is a common issue that affects Outlook Web Access (OWA) and the web version of Outlook.

It occurs when your browser gets stuck in an endless loop of redirects between different servers or domains. This can happen for several reasons, such as:

• Your user account has too many roles or permissions assigned to it.
• Your browser cache or cookies are corrupted or outdated.
• Your internet connection is unstable or slow.
• Your browser settings or extensions are interfering with Outlook’s connection to the Microsoft servers.

How to Fix Outlook Error 500?

There are several possible solutions to fix Outlook Error 500. Depending on the cause of the problem, you may need to try one or more of the following methods:

Solution 1: Check Microsoft’s Service Health

Before you try anything else, make sure that the error is not caused by a problem on Microsoft’s end. Sometimes, Microsoft may experience service outages or disruptions that affect Outlook and other Office 365 applications. To check the service health, follow these steps:

Step 1: Go to admin.microsoft.com and sign in to your account.

Step 2: Select Health > Service Health.

Step 3: Select All services and check the Microsoft 365 Suite’s health.

If there is an issue with Outlook or any other service, you will see a red exclamation mark next to it. In that case, all you can do is wait until Microsoft resolves it. However, if the service health is fine, try the next method.

Solution 2: Check User Permissions

Outlook Error 500 can also occur when you no longer have access to a mailbox. For example, if you work for an organization, the administrator may have removed or changed your access to your email address. In that case, you need to contact your administrator and ask them to restore your access. Alternatively, you can try signing in with a different account that has access to the mailbox.

Solution 3: Troubleshoot Your Internet Connection

Another possible cause of Outlook Error 500 is a poor or unstable internet connection. If your connection is slow or interrupted, your browser may not be able to communicate with the Microsoft servers properly. To troubleshoot your internet connection, try these steps:

Step 1: Restart your router or modem and wait for a few minutes.

Step 2: Try loading a different website on your browser to see if it works.

Step 3: Try using a different device or network to access Outlook.

Step 4: Run a speed test to check your internet speed and latency.

If you find any problems with your internet connection, contact your internet service provider (ISP) for assistance. If your internet connection is fine, try the next method.

Solution 4: Troubleshoot Browser Problems

A corrupted browser cache or cookies can also cause Outlook Error 500. Cache and cookies are files that store information about the websites you visit. They can improve your browsing experience by remembering your preferences and speeding up page loading. However, they can also become outdated or corrupted over time and cause errors. To troubleshoot browser problems, try these steps:

Step 1: Open your browser and press Ctrl + Shift + Delete simultaneously on the keyboard to open the clear browsing data window.

Step 2: Choose a time range (e.g., last hour, last day, all time) and select Cookies and other site data and Cached images and files.

Step 3: Click Clear data and wait for the process to finish.

Step 4: Restart your browser and try accessing Outlook again.

If clearing cache and cookies does not work, you may need to disable or remove any browser extensions that may interfere with Outlook’s connection. To do this, follow these steps:

Step 1: Open your browser and click on the menu icon (three dots) at the top right corner.

Step 2: Select More tools > Extensions.

Step 3: Disable all extensions by toggling off the blue switches next to them.

Step 4: Restart your browser and try accessing Outlook again.

If disabling extensions works, you can enable them one by one and see which one causes the problem. Then, you can either update, remove, or keep it disabled.

If none of these steps work, you may need to try using a different browser or updating your current browser to the latest version.

Solution 5: Remove User Roles

One of the most common causes of Outlook Error 500 is having too many user roles assigned to your account. User roles are permissions that allow you to perform certain tasks in Office 365, such as creating groups, managing users, or accessing reports. However, if you have too many roles, Outlook may get confused and go into an endless redirect loop. To fix this, you need to remove some of the roles from your account. To do this, follow these steps:

Step 1: Go to admin.microsoft.com and sign in to your account.

Step 2: Select Users > Active users.

Step 3: Select your account from the list and click on Manage roles under the Roles section.

Step 4: Remove all roles except for Global Administrator and click Save changes.

Note: This method only applies if you have admin access to your Office 365 account. If you don’t, you need to contact your administrator and ask them to do this for you.
