Is it recommended to implement DMARC records for my Office 365 Exchange domain?

Hello,   I have SPF and DKIM records defined for my custom Office 365 email domain, but it is also recommended to implement DMARC records in my DNS zone file as well?    Cheers!

    It certainly is, but instead of explaining why I’m just gonna link this info 😉
