emails from outlook to bigpond.net.au

Thanks Glenn and David

REALLY glad this issue is now fixed. Let's hope it doesn't happen again. Have a great day!.

Hi Kate,

As embarrassing as it may sound I've actually just been informed by our internal team about this being fixed as well. Slight delay as many have suspected due to a certain U.S. holiday.

At any rate, I'll monitor this thread for the next 72 hours to se if anyone else here is still having the same problem that Kate has experienced. If you're issue is not part of the original issue Kate was contacting about I'll make your reply a standalone thread so you can get the help you need faster.

Special shoutout to David Shx for his persistence. Thank you, sir.

Respectfully,

Glenn

Hello,

Yes I am having same issue e-mail from my Hotmail account any bigpond.com domain - all other e-mails are fine. Can Microsoft please assist?

I have the same problem. If needed, I can send the whole diagnostic report received by an outlook email address when trying to send emails to me.

Hi Glenn

Thanks for your response. I have just been on the phone to Telstra, who state that it isn't their problem, its a problem with Outlook email (interestingly only emails to bigpond.net.au and bigpond.com are being blocked - all other emails are getting through, including to hotmail and gmail accounts as well as emails to company email addresses).

So back to reviewing my outlook account to determine why these emails are being blocked.

regards

Kate

Emails sent using Outlook & outlook.com account (on HP Laptop, iMac & iPhone) to a family bigpond.net.au address are not getting through for last 3 days. Web-version does not appear to have this problem.

I'm not very tech so struggling with all the articles with similar messages & solutions.

Does anyone have a simple explanation/solution I could follow?

Delivery has failed to these recipients or groups:

"******@bigpond.net.au"
Your message wasn't delivered. Despite repeated attempts to deliver your message, a connection to the remote server couldn't be made.

Contact the recipient by some other means (by phone, for example) and ask them to tell their email admin that it appears that your email system is unable to connecto their email system. Give them the error details shown below. It's likely that the recipient's email admin is the only one who can fix this problem.

Hi Kate AK!

We’re glad that you’ve reached out to the Microsoft Community Forum where our members work together to address your technical support needs.

We understand that you're getting a non-delivery report (NDR) or bounce message when sending an email -- using both Outlook.com and the Outlook app -- to a bigpond.net.au email address.

The bounce message you get actually indicates that the issue is on bigpond.net.au's end and not on Microsoft's. With that in mind the owner of the bigpond.net.au email address needs to contact the email provider -- Telstra -- on how to unblock senders.

Also check with Telstra if their email servers are down since the bounce message you got indicated as much.

We look forward to your response.

Sincerely,

Glenn Rue
