only Dmarc is failing, spf and dkim are set up correctly.

Re: SPF Not working

i am wondering why are you using office 365 spf record to send out using your EFA? please provide more details if you need support. wihtout info/details/screenshot we wont be able to help. SPF records /IP are published ips which means you dont have to mask them, everyone on the internet can find them.
