What to do in case of an error: “Outlook reports: sending and receiving an error message (0x800CCC65)”? This means that your application will not connect to the SMTP server that you have configured for your email account.
Error 0x800CCC65 is an error message that occurs when setting up an email client (e.g. Microsoft Outlook) to use with email services (e.g. HostPapa Advanced Email). This is often due to configuration issues with ports, mail client settings, or an Internet Service Provider (ISP) blocking SMTP port 25.
What Causes this Error
The reason for this problem is that your email client cannot authenticate with the server. This is usually due to the fact that SMTP authentication is not enabled in MS Outlook.
Another possible cause of the problem is antivirus or firewall that checks outgoing email connections. If you configured your email client correctly as described above and the problem persists, turn off the antivirus and firewall installed on your local computer and try sending the email again.
The complete error message should look like this:
Sending error (0x800CCC65): Your outgoing mail server (SMTP) reported an internal error. If you continue to receive this message, please contact your server administrator or Internet Service Provider (ISP). The server responded: 503 A valid RCPT command must precede DATA. “
Configure your email client for automatic authentication
Select the “My server requires authentication” checkbox in your mail configuration for the outgoing mail server. You can send an email without opening your mailbox first.
You need to use password authentication, where username is the full email address you are accessing and password is what was generated when you set up the email address. username mail. Depending on your mailer, there may be an option to use the same username and password as your incoming mail server, but not all mailers have this option.
