However, many users experience a frustrating issue known as the **[Microsoft 365 login loop](https://www.solutionsfreak.com/windows/)**. This issue occurs when you attempt to sign into your Microsoft 365 account, but instead of granting access, the system continuously redirects you back to the login page. No matter how many times you enter your credentials, the page keeps reloading. This can be highly disruptive, especially when you rely on Microsoft 365 for work or studies. In this detailed guide, we will explore the **possible causes** of the Microsoft 365 login loop, step-by-step **solutions to fix it**, and **preventive measures** to avoid facing the issue in the future. ## Common Causes of the Microsoft 365 Login Loop The login loop can be triggered by several factors, often linked to browser or system settings. Some of the most common causes include: ### 1. Corrupt Browser Cache and Cookies Cached data or stored cookies sometimes conflict with updated login credentials, leading to repeated redirections. ### 2. Outdated Browser If your web browser is not updated, it may fail to handle the modern authentication process required by Microsoft 365. ### 3. Multiple Accounts Conflict Using multiple Microsoft or organizational accounts in the same browser can cause sign-in conflicts, resulting in the login loop. ### 4. Incorrect Authentication Settings If your organization uses advanced security policies or two-factor authentication, misconfigured settings may prevent proper login. ### 5. Outdated Office Apps or Add-ins When Microsoft 365 desktop apps are outdated or a faulty add-in interferes with authentication, login issues can occur. ### 6. Corrupt User Profile or Windows Settings Problems with your Windows user profile or system settings can also contribute to login loops. ## Step-by-Step Solutions to Fix Microsoft 365 Login Loop Below are some of the most effective ways to resolve the login loop problem. ### 1. Clear Browser Cache and Cookies The most common solution is to clear old browser data. * Open your browser settings. * Locate the “Clear browsing data” or “Privacy and security” section. * Select **Cookies and Cached Images/Files**. * Clear data and restart the browser. * Try logging into Microsoft 365 again. ### 2. Use Private or Incognito Mode Opening Microsoft 365 in a private window bypasses stored cookies. * In Chrome or Edge, press **Ctrl + Shift + N**. * In Firefox, press **Ctrl + Shift + P**. * Try logging in with your credentials. If it works in private mode, the issue is definitely with cached data or conflicting accounts. ### 3. Update Your Browser Ensure your browser is up-to-date. * Open browser settings. * Navigate to the “About” section. * Allow the browser to check for updates. * Restart after updating. ### 4. Sign Out of Multiple Accounts Using multiple Microsoft accounts can trigger the loop. * Go to account.microsoft * Sign out of all accounts. * Clear cookies. * Log in only with the required account. ### 5. Check Authentication Settings If your organization enforces strict login policies, verify your authentication method. * Ensure two-factor authentication is set up correctly. * If you use an authenticator app, check that it is synced. * Contact your IT admin if organizational policies are preventing login. ### 6. Remove Faulty Add-ins from Microsoft 365 Apps Some Outlook or Office add-ins may block authentication. * Open Word, Excel, or Outlook. * Go to **File > Options > Add-ins**. * Disable unnecessary add-ins. * Restart the app and try signing in again. ### 7. Update Microsoft Office Applications Outdated apps may not properly communicate with Microsoft authentication servers. * Open any Office app. * Go to **File > Account > Update Options**. * Select **Update Now**. * Restart your PC after updates are installed. ### 8. Reset Microsoft 365 Login Credentials Windows sometimes stores outdated credentials. * Open **Control Panel**. * Go to **Credential Manager**. * Delete all stored Microsoft Office or Microsoft 365 credentials. * Restart and log in again. ### 9. Repair Microsoft Office If apps are corrupt, repairing Office may help. * Open **Control Panel > Programs and Features**. * Select Microsoft Office 365. * Click **Change > Quick Repair**. * If the issue persists, try **Online Repair**. ### 10. Recreate Windows User Profile If none of the above works, create a new user account in Windows. * Go to **Settings > Accounts > Family & other users**. * Add a new user. * Log in with your Microsoft 365 credentials in the new profile. ## Preventive Tips to Avoid Microsoft 365 Login Loop To reduce the chances of encountering this problem again, follow these preventive steps: * Regularly clear browser cache and cookies. * Keep your browser and Office apps updated. * Avoid logging into too many Microsoft accounts on the same browser. * Sync time and date settings on your PC. * Use the official Microsoft Authenticator app for two-factor login. * Keep your system free from malware or third-party apps that can disrupt authentication. ## Final Thoughts The **[Microsoft 365 login loop issue](https://www.solutionsfreak.com/)** can be extremely frustrating, but in most cases, it is caused by simple problems like corrupted cookies, outdated apps, or conflicting accounts.
