Not for me:

kauer at kt1:~$ dig +short microsoftsupport.com mx
0 microsoftsupport-com.mail.protection.outlook.com.

There is no requirement for an email domain to also be used for
anything else, so there is no requirement for an A record of the same
name.

Sorry, coming in late - what is the actual problem? Does something not
work?

Regards, K.
