When you try to send emails from Outlook using a POP3 or IMAP account, you receive the following error message:
Error message: 0x800CCC80 – None of the authentication methods supported by this client are supported by your server.
The error described in the Symptoms section may occur if your Outlook email account is not configured to connect to the incoming server before sending emails, but your Internet Service Provider (ISP) requires you to authenticate via SMTP before sending emails.
It is possible to configure the encryption method when connecting and disconnecting to the server. It can be predefined or manual, depending on the customer’s needs. The encryption method is programmed for security reasons. This encryption ensures that the current client connects to the server. You can set the test message via Outlook.

Also check the SMTP settings, port number, SSL settings and enable the “My outgoing server (SMTP) requires authentication” option.
Username: the complete email address
Port: 25 (without SSL) 465 (with SSL enabled)
Incoming mail server (POP3): mail.yourdomain.com
Outgoing mail server (SMTP): mail.yourdomain.com

Step 1: Open the File menu, click on Info, then on Account Settings.
Step 2: Double-click the email account and click on Other Settings.

Step 4: Now select the ok button and press Next, then click Finish.
