How to resolve "Your message wasn't delivered because the recipient's email provider rejected it."

Question

I have the following error message when send a email to specific company's user email address.

And I have asked to the company's system admin to allow to receive my email domain but they said that they have no restriction to block my email domain in their email server side. And the company's system admin have asked to MS customer center how they resolve this issue and then MS customer center said that it is sender side issue and this error is not recipient side issue. So, I want to know what is this exact meaning and how do I resolve this from my side. Please let me know any solution for this issue.

Hello Jay Kim,

Thanks for sharing this details. To protect your domain details, we have removed some personal information from your shared screenshot.

Yes, your TXT record is not correctly update. Kindly contact your local domain provider and ask them to update correct TXT records (as visible in O365 side) from their local DNS site. Once they update correct record from there end, it will sync up with Office 365. (Note: sync time totally depends on local domain provider server). Once record shows in green status or (ok), send one test email and check.

Thank you so much for your co-operation.
