How to Fix Microsoft Login Error Code 0x80048820
Microsoft’s error code 0x80048820 typically appears as a sign-in error when trying to log into your Microsoft or Outlook account. This error often occurs when a user attempts to log in multiple times or when several identity verification requests are made. Since this code indicates a problem with either the account or the network, it may temporarily lock you out.
The problem can arise due to network issues, unverified login attempts, or an issue with the account itself. To troubleshoot, check your internet connection and verify the account’s status. However, it’s often best to wait a few hours before attempting to sign in again, as the issue may resolve on its own.
1) Verify Your Microsoft Account’s Status
When you encounter a sign-in error like this, the first step is to verify if your account’s credentials are correct. Sometimes, security settings may change if the account has been compromised, especially after multiple failed sign-in attempts. 
Wait for a while and try logging in again using your browser to check for any unusual activity or discrepancies. If you notice anything suspicious, take immediate action to recover your account and review your order history for any unauthorized purchases. It’s also a good idea to contact Microsoft support if you need further help.
2) Change DNS
If you’re still unable to log in after waiting for the backend issue to be resolved, the problem might be with your internet connection. It’s important to check your network by running an online speed test or simply browsing the web. 
Microsoft recommends changing your DNS to help isolate any issues with your network connection. If you’re unsure how to do this, Appuals has an in-depth guide on how to change DNS in Windows.
3) Disable Third-Party Antivirus Temporarily
Many user reports suggest that Microsoft services like Edge, Store, Outlook, Live Mail, OneDrive, Microsoft Rewards, and Minecraft can sometimes be affected by third-party security software. While Windows Defender typically doesn’t interfere with the sign-in process for these apps, third-party antivirus software might cause problems.
To troubleshoot, it’s worth temporarily disabling your third-party antivirus software to see if the issue persists. Sometimes, security software can block certain network requests, preventing a successful sign-in.
Don’t worry—this is just a temporary step to help identify the cause of the issue. If disabling your antivirus resolves the problem, you can either add an exception for the affected service or re-enable the antivirus and make the necessary adjustments.
4) Try Microsoft Edge Preview Version
If the issue seems app-specific, it might be worth trying to log in to your account using a different service or browser. Microsoft support recommends using the Preview version of Microsoft Edge, which operates independently from the standard version but still allows data synchronization when you log in. 
Since most users have reported this issue on Microsoft services like Xbox, Store, or the Edge browser, trying a different browser might help. Some popular alternatives include Google Chrome and Mozilla Firefox.
5) Contact Microsoft Support
If none of the previous steps resolve the issue, your next option is to contact Microsoft or Xbox support, depending on which service is affected. Microsoft’s support team has the tools and expertise to handle user-specific issues and can help you isolate and resolve the problem.
