We now run into the problem that certain mails are no longer received. These are sent from on cpanel but never arrive at office 365. We have checked all records of our panel and they are correct. When we send a mail we also receive no error message from office 365. Mailing from office 365 to cpanel succeeds. Oddly enough this worked yesterday, and now it has stopped (without us making any changes)
we have checked the e-mail flow and we can not find the e-mails there. In one way or another, they really do not arrive. We used all kinds of tools to see if the spf records and dkim records were correct and this was correct. It's pretty annoying because the leads come in at office 365 and this does not seem to work. What can we do?

I have tested sending from one domain to another inside office 365 and that works fine. But when I send using another system than office 365 it won't work (Direct admin / Cpanel)

So O365 to O365 works, but not for example Gmail to O365?

Gmail to O365 yes.
But Cpanel, Direct admin to O365 not it don't even reach the exchange (according to office 365 support)

Just got called from Microsoft UK they checked the DNS records (DNS was fine). They are still searching for the problem

I have sent them a YouTube video from our side, that everything works on other office 365 installations (from other organizations). Cpanel also works with gmail. They are still searching for the problem and yes it takes a long time
