Continue reading the guide to equip yourself with the knowledge needed to resolve this error. Keep in mind that these solutions are temporary, as the error may recur when you try to access Outlook again. Before you begin, try logging out and logging into your Outlook account again as doing this simple step resolved this error for many users.
1. Check Microsoft’s Service Health
To determine if the error is due to a Microsoft service outage, visit the Service Health panel. If a Microsoft service is down, you must wait until it is fully restored.
2. Remove Excessive User Permissions
The error can also occur if a user has too many administrator roles assigned, which can cause endless browser redirects. You can correct this by removing some permissions. If you are not an admin, contact the admin managing your Microsoft 365 subscription and request the removal of all admin roles except for Global Administrator. If you are the Global Administrator, you can make these changes yourself.
3. Use Microsoft’s Diagnostics Tool
The Microsoft Support and Recovery Assistant is a diagnostic tool that can help troubleshoot problems with a wide range of applications.
