Moving to O365 EOP from on-Premises email gateway
Hi,
I have mcafee as email gateway and have hybrid infrastructure for exchange. Right now first email comes to gateway and then it goes to O365.
Now I am planning to decommission the gateway and use O365 EOP instead.
Can anyone please give me best way to do that? I guess I need to change mx record but I have one big problem because large blacklisted, whitelisted and other rules in gateway and how that rule can be migrated to Exchange Online Protection In O365?
Thank you.

Thank you very much.
As I have to apply this next month, I have last question,
Do you think that EOP alone can handle the organizational need without any third party gateway?
Thanks.

How many users you have total including clod and onpremise?
Do you have enough EOP licenses to cover both since u r moving mx to o365, enough EOP licenses should be available
Cross check that and if required you need more licenses to be in compliance

We are planning to move our mailboxes to O365.
Do we need license for EOP? I think EOP does not require license, but I am not sure right now. I have to see more documentation..

Nope, EOP licenses are required
what plan you have for exchange online (Normally E3 / E5 etc), normally EOP licenses ships with that plan with equal amount of licenses Because EOP is different service altogether which secure your mail flow with Exchange Online Protection Gateway
When you purchase enterprise plans from MS they take responsibility of your online mailboxes, but what you are trying to do, you are diverting mail flow entirely to cloud while keeping hybrid environment, so technically when you relay mails to on premise server, its not covered by EOP but utilize EOP services and hence you have to have EOP licenses equal to total organization users (on premise + cloud)
So either you keep MX to onpremsie or get additional EOP licenses
Check with your MS TAM or whoever from you purchase MS licensing about EOP licensing requirements

Thank You Mahesh for your valuable information, I will definitely contact MS for licensing information.
Although we will maintain hybrid scenario, our all mailboxes will be in exchange online with P1, P2 and E4 licenses.
I was thinking that, MS provides EOP with the license in exchange online, so why to pay third party!!!
Thank You.
