Alias from other domain to O365 - 1 user out of a few? MX record question
Posted on 2015-01-15
We got an Exchange Online plan and have another domain we want the user to be able to receive e-mail from and send e-mail as.
So Sally@Domain.onmicrosoft.com wants to receive e-mail from account Sally@anotherhost.com and be able to SendAs that address.
Problem is, there are other users over at "anotherhost.com" who don't need to move over to O365, so I'm not sure if changing the MX records can be done for just 1 user, or if we do anything with the MX records, if the O365 user will continue receiving e-mail and the other users at anotherhost.com will no longer receive e-mail at their current host inbox.
Or will the other users still be able to send/receive their e-mail unaffected?
