We have a customer with about 4000 Exchange 2013 Mailboxes onprem. He also posess an Office365 E1 Plan with Exchange Online Plan 1 included.
The customer whishes not to have an Exchange Hybrid Configuration, instead he will stay onprem but using Exchange Online Protection as an mailgateway with antimalware / antispam function.
Can we use Exchange Online Protection with this license, poiniting our mx Record to Exchange Online Protection, which send us the verified mail to our onprem Exchange 2013 Servers?
Can we also send the outgoing mail traffice to Exchange Online first for verification?
Do we have all the function of EOP with the Office365 E1 Plan?
Do we need first to establish dirsync for replication the user to Office365?
