Eventbrite Emails Quarantined for Single User

Hi Experts,

I have a bit of a strange issue. When registering for an event, confirmation coming from go to Quarantine for ONE specific user.

For example, I'm using Exchange Online, I have a few domains, but the following users are receiving emails directly into their Inbox from the above noreply@:




However noreply@ emails are going to quarantine for 

I bolded as other users from the same domain, and different domains within the same Exchange Online account, are getting these emails directly to their inbox.  This indicates to me, it is a user-issue, but within Exchange - not Outlook.

That said, I spent a few hours with Microsoft support, and whitelisted:




I think we also added an Anti-Spam Policy By-Pass (I'm not sure), but the issue persists. Finally, Microsoft had me send their engineers some reports, and in conclusion they advised me to contact Eventbrite for them to 

Sender organization must update their SPF, DKIM and DMARC record so that their emails does not get mark as spam and move to quarantine.

I will try contacting Eventbrite, but personally I feel that this will not work. This is for a single email address world-wide. It is not even domain-level. I think Microsoft is just washing their hands from this.

Finally, I found this article from Eventbrite - to whitelist their IPs, but under Exchange  Online I have only found Connection filters related IP whitelisting, which I assume its related to email clients.

Any help would be appreciated.

Thank you!

You might need to contact the user (​)​​​​​​ that you will grant yourself the permission to login to his OWA to look up the settings as it is very likely a user level problem.

Or, you need to view the full email headers of the email sent to​ to lookup what is the problem.​​​
I don't understand???

I do have access to OWA?
