lyn********@optusnet.com.au - 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).'

I have tried LOTS and lots of things to fix it.

AS PER INSTRUCTIONS FROM OPTUS & OUTLOOK: 

I have change passwords for incoming and outgoing mail.

I have changed the ports for incoming and outgoing mail

I have asked Microsoft community for help, NOTHING has helped.

MS team sent me an email 07/09/24 at 12.14 telling me to go to the Control Panel configuration area:

Check all the codes and do a test.

Test came back: yes connected.

                           NO can’t send: error is: 

Send test email message: 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). 

I have referred this issue to both Optus and Microsoft and nothing seems to work.

It was all ok until Optus 'Did an update' so the staff say, and it has created a known error. 

I feel I am being fed a line., and Optus needs to fix the issue.

I have not been able to send emails since mid August... and I have done all I can possibly do to fix the problem: Get my emails sending again.

Someone needs to step up, Optus and Outlook need to be working together to fix this issue.

Optus have confirmed my account is NOT suspended or cancelled.

I have gone through the process to AUTHENTICATE my email address, changing ports etc... and nothing has worked. Optus said to aske Outlook to confirm the account is valid. I filled in an online Microsoft form and still NOTHING changed. I have sent email after email… NOTHING works.

I have shut down, done restarts so many times it is crazy.

I have changed my Microsoft password because one of the MS techs said to do this... no change to anything.

In the beginning I had NO Optus, NO webmail

Now, I have webmail and I CAN receive emails to Optusnet/Outlook,

BUT I STILL CAN'T SEND from Outlook.

ENOUGH IS ENOUGH,

PLEASE HELP ME TO FIX THIS ISSUE.

Hi JaxMolly,

I think as long as you can send/receive emails normally in Outlook, then you must have successfully passed the authentication of OPTUS, and Outlook also supports adding most mailboxes, so you don't need to worry about this, unless OPTUS changes the authentication method later, but this requires you to contact OPTUS to get the correct server settings.

Glad your problem is solved, you can click "Yes" below my previous answer to help others who are experiencing the same problem so that they can quickly find a solution.

Thank you for your support and cooperation.

Hi JaxMolly,

Thank you for your cooperation, the information you provided will make it clear to me what the problem is.

The problem may be that in the Outgoing settings, you don't need to change the server address, you need to change the port to "25" and then set the encryption method to "STARTTLS".

This is what I searched on the OPTUS website, I hope it will be helpful to you.

    Thank you Jason for your prompt reply.

    The reason the ports were changed is that Optus said that we needed to AUTHENTICATE our email address as part of their update against spam.

    To AUTHENTICATE means that we can send more than 8 emails aday AND our sent emails will be recognised by other email servers, domains.. what ever you call them to say that they are not spam, that they are not a risk.

    Optus said we needed to get Outlook to recognise/approve, or similiar words, our Optusnet/Outlook email status,

    Optus said we had to use encryption/security: SSL/TLS on both outgoing & ingoing.

    Optus said port 25 was no longer to be used

    I am happy to try it tomorrow and see what happens... nothing ventured nothing gained..

    Maybe you could do some research for me on AUTHENTICATE in the Optus space AND look into what needs to be done by MS for Outlook to recognise/approve, or similiar words, our Optusnet/Outlook email status.

    IF you have time, I would appreciate it if you could CHECK to confirm that my email address IS authenticated with Optus AND approved/recognised by Outlook.

    Your suggestion sounds good.

    I will try it first thing tomorrow.

    I WILL be delighted if it fixes the issue.

    Also, I look forward to seeing what you can find out about the above. :)

    Thank you,

    Lynda

    Dear JaxMolly,

    Welcome to Microsoft Community.

    I have been informed that you are getting a Smtp server error when sending emails in Outlook, the message indicates that Outlook is currently unable to communicate with OPTUS outgoing servers, and therefore is unable to send emails through OPTUS outgoing servers.

    May I ask which version of Outlook you are using? You can find the way to check it in the link below.

    What version of Outlook do I have? - Microsoft Support

    What are your current Outgoing mail settings?

    You can check it in the control panel or in Outlook by clicking on “File”, selecting your OPTUS account in the list of accounts and clicking on “Account settings - Server Settings”.

    Please let me know what server settings you are currently using, it includes the server address, port number, encryption method, etc. You can post a screenshot here.

    Looking forward to hearing from you

    Best Regards,
