Cannot send outgoing emails on Outlook - ERROR 0x80042109

Hello Graham,

Check the outgoing server settings - in Outlook 2016 and newer, Go to File > Account Settings > Server Settings. Expand Outgoing mail section. Is your port number correct? (Most servers use 465 or 587). Is "My outgoing (SMTP) server requires authentication" checked?

Please if you have Imap account as you confirm please check and Try port 587 and STARTTLS or SSL

Server smtphm.sympatico.ca
Port 25 (or 587 if port 25 does not work)
Authentication required Yes
TLS/SSL required Yes (Select STARTTLS or TLS if available. If not, select SSL.)

Outlook has a STARTTLS option, so choose it with port 587. Make sure "My outgoing (SMTP) server requires authentication" is checked.

Let me know the result if the issue still persist for the next steps of the troubleshoot

Appreciate your patience and understanding and thank you for your time and cooperation.

Thanks for your reply.

The problem has been rectified now thankfully. The issue was due to the domain moving from one provider to another and an issue with the DNS settings.

I am experiencing the same issue as of this morning Thursday 29/09/22

Based on your description please can you confirm if you send and receive email via your outlook on the web https://outlook.live.com 

I can send an email via outlook app however, I don't receive and never have

-Please may I know the type of your account (Pop3 account, Imap account or exchange account)

IMAP account

-please may I know your outlook version What version of Outlook do I have? (microsoft.com)

Microsoft 365

Task 'Work - Sending' reported error (0x80042109) : 'Outlook cannot connect to your outgoing (SMTP) email server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).'

If you can help I'd be most grateful.

Thanks,

Hi there

Thanks for your reply.

1. Yes I can send and receive via Outlook on the web
2. I think it's an IMAP account. It states IMAP/SMTP.
3. It states that I have the latest version of Office installed on my computer. Where do I find which version of Outlook I'm on?

When I go into Office Account, there is a message 'Account Error'. I click on 'Fix Me' and type in my email address '******@chascannco.com' and the message 'chascannco.com isn't in our system'. I click on 'Can't access your account' and 'Get back into your account' and type in my email address, click on 'Enter Characters' and it starts to buffer forever! So I can't add the characters to continue.

Hope this helps.

Graham
