You have an important email to send, but you get the error 0x8000000b when you try to send your email. What do we do now? To first understand why this happened, we must understand the nature of this error.

This error is related to synchronization problems and is displayed when you try to configure your email application. Whether you use Gmail or Yahoo, this can happen if you configure it in the Windows 10 email application.

When you click the Send button, your email application automatically tries to connect to the mail server to get the server settings, but this error sometimes occurs. But don’t worry, we’ve put together a list of tips and solutions for you. So let’s get to the solution.

The error code 0x8000000b indicates that the email application could not connect to the Gmail IMAP server. Make sure your firewall allows outgoing connections to ports 993, 465 and 587. Some antivirus programs can also cause this problem, so try to temporarily disable email scanning to allow a direct connection.

You can obtain other error codes such as 0x8007042b, 0x80040154, 0x8000ffff, 0x8007000d, 0x80c8043e, 0x80070435, 0x8007006d, 0x80070425 that are associated with the same error message. Regardless of the error code you receive, the underlying problem is that you cannot add your Gmail account. In general, the error prevents you from using your Gmail account in the email application.

Disable Antivirus or Windows Defender
