Strange MX records issue

After pointing the MX records to Office 365, the email is not flowing anymore.

When I do a "Find and fix issues" in the Office 365 portal, I get this error:


The MX records are clearly not setup this way at the DNS registrar.

I'm not sure if it's clear from the picture but basically it says that the domain is added at the end one more time.

Any help would be appreciated.

I think YOU really did set it up wrongly. Probably because your DNS registrar web interface allows you to fill in servers BEFORE the domain name. (usually a text block, and behind it the domain name your administrating, as that's usually what is expected in this admin panel).
If there's no way to have FULL freedom to fill in your DNS settings, just get in touch with support (either they will show you how to fill in an entry unrelated to your own domain name, or they will manually add it for you).
It's quite logical though. DNS admin panels are designed to make it easy for you to add entries for
where you fill in only the first part, to help you minimise making typos. In this case though, you need to get outside this ease of use parameters.
To double check that your MX record is really wrong, you can do a nslookup against google's dns and see that you're really wrong.

Microsoft put out a statement earlier in the year regarding this.

All domain specific MX records must be changed to
yourdomain-tld.mail.eo.outlook.com or
yourdomain-tld.mail.protection.outlook.com to avoid service flow disruption.

IIRC this was sometime around July.

Also ensure that you have set the spf correctly

"v=spf1 include:spf.protection.outlook.com -all"

I forgot to add the .(dot) after com. WOW! Some DNS providers need that .(dot), some not.

Thanks everyone for the help!
