do you have an inbound mail gateway that's either hosted or on-prem? if so check there or does your inbound mail go directly to your exchange server? if it goes directly to your exchange server check to see if there are emails stuck in the transport queues.

Thank you for the help, time may have been a factor. I removed an expired cert, verified the MX records and a name servers as a recent website change was involved.
Do you have backpressure?
Check events 15000-15010 to verify if you have backpressure.
Check if all the services are running.
