How to Fix the 0x80040b0b Mail App Error
Error 0x80040b0b in the Mail app can be frustrating, but there are several steps you can take to resolve it. Here's a troubleshooting guide to help you fix the issue:
Restart the Mail app: Close the Mail app completely and then relaunch it. Sometimes, this simple step can resolve temporary glitches.
Check your internet connection: Ensure that your device is connected to the internet. Verify that you can access other websites or apps that require internet connectivity.
Update the Mail app: Make sure you are using the latest version of the Mail app. Check for updates in the Microsoft Store and install any pending updates.
Check account settings: Double-check your email account settings in the Mail app to ensure they are configured correctly. Pay attention to the incoming and outgoing server information, port numbers, and authentication method. Incorrect settings can cause synchronization problems.
Remove and re-add the email account: If the issue persists, try removing the problematic email account from the Mail app and then re-add it with the correct settings. To do this:
- Open the Mail app.
- Click on the gear icon (Settings) in the lower-left corner.
- Select "Manage accounts."
- Choose the email account causing the error, then click on "Delete account."
- After removal, go back to "Manage accounts" and click on "Add account."
- Follow the on-screen instructions to re-add the email account with the correct settings.
Disable antivirus or firewall temporarily: Sometimes, third-party antivirus software or firewall settings can interfere with the Mail app's functionality. Temporarily disable your antivirus and firewall to see if it resolves the issue. If it does, consider adjusting the settings to allow the Mail app to function properly.
Reset the Mail app: If the error persists, you can try resetting the Mail app. This will revert the app to its default settings, but it won't remove your email accounts. To reset the Mail app:
- Open the Settings app (press Windows key + I).
- Go to "Apps" > "Apps & features."
- Search for "Mail and Calendar."
- Click on "Mail and Calendar," then select "Advanced options."
- Scroll down and click on the "Reset" button.
Run Windows Update: Ensure that your Windows operating system is up to date. Microsoft releases regular updates that may include fixes for known issues.
Create a new Windows user profile: If none of the above steps work, try creating a new Windows user profile. Sometimes, user profile corruption can cause issues with apps like Mail. To create a new user profile:
- Go to Settings > Accounts > Family & other users.
- Under "Other users," click on "Add someone else to this PC."
- Follow the prompts to create a new user account.
- Log in with the newly created user account and check if the Mail app works correctly.
