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.

Thanks to all those who helped in any way!
David you're a star! Thank you so much for persevering with Microsoft. My hotmail is talking with bigpond again now. Phew. Best regards
Yes ..it's working !
Wonderful..at last.....but what a journey to get it fixed when it never should have happened in the first place.
Thanks Glenn and David
REALLY glad this issue is now fixed. Let's hope it doesn't happen again. Have a great day!.
regards
Kate
Yep! It now works for me too.
A final thought to Microsoft: PLEASE keep your frustrated customers/users informed on what steps you are taking to resolve any issues. What frustrated/irritated me on this issue was not the length of time it took to resolve the problem - it was not knowing if anyone was working on it. It should not have been up to David to persevere, eventually talk to a real person and let the rest of us know what was happening. The need for good communication is a large part of Customer Relations 101 - and, in my mind, Microsoft achieved a "F".
