You technically don't need the on-prem Exchange.
You could just expand the AD schema with all the necessary Exchange attributes.
But Microsoft requires Exchange on-prem for a 'supported' scenario

- Kevin_DavisAug 17, 2020Brass ContributorThanks Thijs. I appreciate the on-premise Exchange is not required for MS365 mail flow and reader access (Outlook), but IS still required for user management. I'm not a fan of half-baked solutions, or leaving some parts incomplete, so will confirm with our other clients who are on 3rd party email systems. The fact they will need a full blown Exchange server on-premise to support MS365 'cloud' mailbox users will be a deal breaker for most, if not all, based solely on additional hardware and ongoing maintenance costs. Microsoft dropped the ball on this one.

I see a lot of customers doing it
