Microsoft Exchange Email Headers Help

Question

Does anyone know what the following Microsoft Exchange Email Headers mean?

X-MS-Exchange-Organization-SenderIntelligence-P2SenderOrgDomainTenantId

and/or

X-MS-Exchange-Organization-SenderIntelligence-P2Sender

I Googled it and Could not find a whole lot of documentation/information on it.... looks like it may be some sort of tracking... but I could be reading that wrong...

Any Microsoft Exchange gurus out there?
