By default Office 365 DMARC validation for internet emails that fails for policy P=Reject will make the email to land in junk folder of the recipient mailbox. Microsoft 365 will treat DMARC policies of quarantine and reject in the same way, which means that if the sender’s DMARC policy is set to reject or quarantine, the emails that fail DMARC will be sent to the junk folder of the recipient mailbox which is by design as of now and can be found in the Microsoft Article.
Microsoft believes that the main agenda of doing this is to ensure that any legitimate emails which misses in DMARC alignment shouldn’t be lost and its better either to quarantine them or to get them delivered recipient’s junk mail folder. There are few cases wherein few organizations would still need the DMARC policy to be stringent due to their security regulations.
Microsoft validates DMARC and overrides the failure with a header value for a domain whose DMARC TXT record has a policy of p=reject oreject. Instead of deleting or rejecting the message, Office 365 marks the message as spam.
