You are the receiver, and you are choosing to reject messages that do not pass DMARC tests according to OpenDMARC.
So, I think that you are completely in control of whether you receive this message or not. Microsoft possibly sending a message which was not compliant with their published DMARC policy does not change that. Also, my guess is that the SPF pass is just a pass, not an aligned SPF pass as per DMARC.
