Exchange online
Hi BenKrah,
Before, I used G Suite. Now, I change to O365. But I don't want to change all users to O365, and a little user uses G Suite. I created MX records to point a domain to Exchange Online to receive emails. And I create all users in O365. So users use G Suite has both accounts in O365 and G Suite. I want users to use G Suite can receive emails in Gmail and Outlook. What should I do? Can you guide me?
Hi Linh123,
what is the point in doing so resp. why did you switch MX to Office 365 if you want to keep G Suite for your users?
You can only receive mails in one of the systems (as MX can only point to one system) and would have to configure mail forwarding as I described earlier. With e-mail it is an either/or choice, anything else will likely cause confusion and unnecessary administrative efforts.
From my point of view you should make a choice if you want your user mailboxes and the respective functionality to be hosted in Gmail or Exchange Online. For the rest of the G Suite it makes no difference, you can use all office apps like before (i.e. Docs, Chat, Drive, etc.).
But if you choose to go with Exchange Online it makes way more sense to also use all of the office apps from Microsoft (you already mentioned Outlook). But you will need according licenses to do so.
Hi BenKrah
I have only one domain that added to both the G Suite and O365. I want to set up dual delivery in Exchange Online.
Hi Linh123,
as already mentioned, a MX record can only point to one system, not to both (if the domain is also used for authentication in G Suite, you can keep the configuration itself).
You already configured the MX record to point to Exchange Online so all mails will be routed there and from there you will have to work with forwardings as I described before. If users should get mails in both environments you must assign at least an Exchange Online license to each user and configure forwarding for each user mailbox.
You also need a separate email domain in G Suite for forwarding mails because if you configure mail forwarding for a user like this [when a mail for mailto:john.doe@domain.net is received, forward the mail to mailto:john.doe@domain.net] you would create a mail loop. You need an alternative email address so Exchange can route the mail to an external mailbox (Gmail in this case).
