how does dig ANY microsoft.com looks on your site ?
when I query ie google's public dns resolver I get

this is missing second TXT spf record
bind and powerdns-recursor seems to reply with all records for
microsoft.com they have, so if You earlier request for A and TXT you
get A and TXT from your local resolver despite that m$ servers sent
truncated answers for ANY queries that got ignored by bind, and didn't
provide TCP so I guess all you see is Your local cache made form
previous non ANY queries
Response for dig ANY microsoft.com varies significantly across dns
servers, sometimes we get TXT records, sometime we don't, some don't
have SOA ect.
