I recently changed my domain’s MX to point to EOP. Mail flow is working to my 365 and on prem mailboxes fine however when emailing a 365 mailbox ,the email goes to EOP then on prem which routes it back to EOP. In 365 I set my accepted domains to authoritative however the result is the same so I set them back to internal relay. Please help. In my on premise org those domains are set to authoritative.
