Hi,
My customer currently as 2 domains and are receiving emails on both domains. Let's call them Domains 1 and 2 for simplicity.
Now they want to move to Office 365 and want to retain only Domain 2.
Here are the asks:
1. Whatever emails come to the Domain 1 needs to be routed to Domain 2. Is this activity as simple as setting up a server rule on Domain 1 Exchange Server on-premise? If yes, is there a best practice guide for this?
2. While they want to move to Domain 2, they are also interested in getting rid of their on-premise Exchange Server for Domain 2 and move to Exchange Online on Office 365. They also have an on-premise AD Server. What actions are needed to move Active Directory to Office 365? Is it even possible?
3. If moving the AD to Office 365 is not possible, then what all activities need to be performed to synchronize AD and Exchange Online? Is there a guide for this?
Thanks.
