I am having the same issue.
We are using a business account.
Four separate bounce backs:
X 2 Yahoo accounts.
X 2 AOL Accounts.
Any advise would be appreciated.
I am getting the exact message as "mpur" posted. From what I am reading am I to assume this error is really a YAHOO account issue. They must have changed some security feature on their accounts and they are blocking anyone that doesnt have a YAHOO account. I am a travel agent and all of my clients emails are bouncing back as undeliverable. It is not in their spam/junk folder. Please find a solution to this quickly. thanks!
I just got Microsoft on the phone (I called into 800-865-9408, waited about 30 minutes for someone) and this is what they had me do to fix this issue:
Login to https://admin.microsoft.com
On the left pane, click Show All > Settings > Domains
My main domain had an issue under the Status column to show that we were having a problem
Click the 3 dots and choose Manage DNS
Click Continue twice and it will take you to your domain setup. I had a handful of SPF records listed and it says that you can only have one. This was my problem.
I logged into my DNS Server (my host uses cPanel) and went into the section where the TXT and CNAME entries are (I think it's called Zones in cPanel)
I looked through and found all of the SPF entries (literally just ctrl+F SPF to find them) for the main domain - sub-domains didn't matter for me.
I went to Chat GPT and asked it to help me combine the SPF records and copy/pasted all of the ones I had in there (YMMV with Chat GPT). I used the output and pasted it into a TXT entry and deleted the others.
I went back to Microsoft and it recognized that I only had the one SPF record and it looks fixed now.
Hope this helps someone!
someone replied this regarding this issue - is this the solution?
Unfortunately there is nothing that Microsoft/Google/Yahoo can do. Every company is going to have to add something called a CNAME record to their domain with a DomainKeys Identified Mail (DKIM).
Here is a tutorial over at GoDaddy on how to updated the records: https://www.godaddy.com/help/create-and-add-dkim-records-to-my-microsoft-365-organization-41748
No way would they block outside email users. It wood make yahoo mail useless. And the error message would be different. What it shows now is that when the Microsoft SMTP server tries to connect to the Yahoo server there is a socket connection error, the kind of thing you'd get with a firewall blocking you, and it's not that.
I'm in the middle of business tech support work Microsoft on this and it's my impression they have no idea what it is. They have me fixing things that can't possibly be the problem. I pointed tech support to this thread to show site that I'm not the only one.
