I am having issue that Yahoo emails are not reaching recipients. I am getting an error message but after 24hrs not even straight after. It's only come to my attention because in follow up calls, they are telling me that the emails never arrived..
Please advise me how to sort it out as is very important I can reach those yahoo recipients.
Your message couldn't be delivered. Despite repeated attempts to contact the recipient's email system it didn't respond.
Contact the recipient by some other means (by phone, for example) and ask them to tell their email admin that it appears that their email system isn't accepting connection requests from your 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.

If you use your own domain name and your DNS records are invalid or missing, Microsoft can't resolve the problem so they aren't doing anything for you. You're responsible for the fix.
I am having the same issues and it is impacting our work/contacts. What is microsoft doing to resolve?
You're welcome. Just to let you know there are currently multiple issues that I'm aware of:
Problem #1 is user's responsibility if they use custom domain
Problem #2 is Microsoft's responsibility and there is nothing you can do to fix it
MarkLucasNY - thanks very much, makes sense, appreciate it!
Ron6576 - it's actually a friend of mine having this issue so I didn't find out who sender was but I will find out and check on EasyDmarc for any issues...
Thank you both!
This has been happening since last Thursday. It's an issue with Yahoo receiving email from Microsoft. It's not something that you can do on your side. Anyone sending from Microsoft 365 to Yahoo needs to implement DKIM on their domain and Microsoft account. This requires that they turn on DKIM on their Microsoft account and add DKIM records to their domain's DNS.
You can try talking to Yahoo but they'll just blame Microsoft. Convincing your contractors that it's something they have to do might be difficult but it's currently the only way it will work - that is, until Microsoft and Yahoo work out their differences.
