Microsoft is particularly annoying. If I send mail from my domain via my server in Rackspace's cloud to my @outlook.com address, Microsoft classifies it as spam. I tell it that the mail is not spam--and the next one still gets classified as spam. I've done this several times now, and it is still classifying them as spam. How many freaking times do you have to tell Microsoft that something is not spam before it learns?

Compare to Yahoo. The first one to my @yahoo.com address was classified as spam, but then after I told Yahoo that it was not spam, subsequent ones come through fine.

I know right? Seriously, Office 365 spam management is a joke. Not only do Microsoft's OWN HOLIDAY PROMOTION EMAILS get marked as SPAM.. but whenever I mark an item or whitelist a domain at the Exchange level it completely ignores the rules.

Has anyone ever successfully got SPAM management working using the native O365 tools?

Well, the holiday promotion emails are spam, so it is sort of working as intended in that regard

Was about to say this. The fact that MSFT even throws their own promo emails into spam just tells me that there is no special preference kind of bias towards their own stuff, which is imo a feature, not a bug.
