Backup Mail Exchanger: It manages all emails sort of a remote mail exchanger, except within the case, the remote service is unreached.

If for any reason, Office 365’s servers aren’t accessible then it delivers the mail locally, similar the native mail exchanger choice.)

Remote Mail Exchanger: All mails sent to your domain remotely is managed by remote mail exchanger; i.e. – delivers them to the mail service searched by the domain’s Mx record. (For example, if Office 365 is your mail service, it’ll deliver the emails to the mailbox on Office 365’s servers instead of your local mailbox.)
