How Do I Fix Outlook Error 0x80040201?

Here are some manual methods you can try to resolve the 0x80040201 error:

1. Verify Email Account Settings

Incorrect server settings may block Outlook from accessing the mail server and thus cause the error.

How to verify:

2. After that, navigate to the File > Account Settings > Account Settings option.
3. Here, select the desired email account and tap on the Change button.
4. Here, authenticate the server settings that your email service provider is offering.
5. Now, ensure that your IMAP and POP settings are up to date.
6. In the end, verify your email account of your Outlook application.

Limitations:

• Even with the proper client-side configuration, server-side issues can still prevent a successful server connection.
• If you are using a service that continuously changes settings, you might need to recheck and reconfigure settings constantly.

2. Fix Outlook Error 0x80040201 By Disabling Antivirus/Firewall 

Antivirus software can prevent Outlook from connecting to the mail server. Temporarily disable your antivirus program to check if it fixes the problem.

Firewalls could also prevent emails from going through. Turn Windows Firewall or other third-party firewalls off and check if this is causing the error.

To disable Windows firewall:

1. First, search for Control Panel in the search box and press Enter to open.
2. In the Control Panel, click on the System and Security option.
3. Here, select Windows Defender Firewall from the Windows Defender Firewall tab.
4. Next, choose the Turn Windows Defender Firewall on or off option.
5. After that, turn off your firewall protection. Press OK to apply the changes.

Limitations:

• Disabling antivirus software or firewalls exposes your system to security threats while troubleshooting.
• This technique has the potential to correct the problem at times but is not permanent.

When trying to send an email with an oversized attachment, there is a possibility of PST file corruption. This is because the size limits set by the email provider are exceeded.
