Why doesn't O365 produce DMARC reporting?

Hi All,   We're working through DMARC for our org, and I'm trying to understand why O365 doesn't produce DMARC reporting for mail it receives - that can be consumed and analysed?   I've spoken to...

    Hi Scott,

    This has been asked for a very long time - I had customers as far back as 2012 asking for it when I started doing large scale migrations to Office 365. As expected there is a Uservoice open for it.

    https://office365.uservoice.com/forums/264636-general/suggestions/11094318-dmarc-aggregate-reports-from-o365-domains

    When Microsoft themselves implemented DMARC they used Agari for the reports. There was quite a well known blog series by Terry Zink on it at the time. Whilst they ended up introducing DKIM into the EOP service on top of SPF and began using DMARC - even to the point of instructing how to put together a DMARC record and tightening it over time, they never got involved in the reporting side of things. Agari was usually recommended for enterprise size clients whilst DMARCIAN was recommended for SMB.

    They never explained exactly they never got into DMARC reporting. I guess this is something to vote for on the Uservoice to try and push it to their attention. It would make complete sense - and even more to analyse that in Power BI.

    Hope I have answered your question.

    Best, Chris

Thanks Chris - the extra info/context is super helpful.

 

We have a tool in place (like Agari) to aggregate the reporting to then use in building out our SPF and DKIM setup in prep for DMARC - we're just missing so much not having reporting/telemetry coming from O365 and feeding into the tool we use.

 

I'm not ready to give up on this one just yet - so will keep poking to see if I can get something more.

 

Cheers,

Scotty

Any news on Dmarc reporting from Microsoft/O365?

      Valimail is a reporting tool (similar to something like Dmarcian), this doesn't address the issue of Microsoft not sending DMARC reports. 

       

      For example I run HelpScout as a help desk for one business, DKIM, SPF and DMARC are all configured. I can see that Google, Yahoo, etc. are receiving emails from Helpscout and they are passing and domain aligned. Great.

       

      But then a customer tells me the emails are going to his junk folder, I check and he is on Office365...

       

      I have no visibility from Microsoft servers if they are happy with the email authentication or not. I assume they are, but I have no idea. I also have no idea if anyone is trying to spoof our domain to Office365 users.

       

      The same problem if I am helping other clients not on Office365 with their deliverability...

       

      I just don't understand why Microsoft wouldn't comply with the DMARC reporting like all the othe big providers?

        This seems odd, as Microsoft promotes this service and Valimail says it completes O365. And their service is free specially for O365 customers!
        Just made an account with them, waiting for any data to appear to the dashboard. 
        If this works, it tells that MS is letting the reports to certain partners, but not all. Then we might discuss about visibility and equality....
