Domain mail on another server problem
Good Morning, We have a domain name which is used on another mail server and not office 365 let's say consto.uk this is in our active directory and and we have azure ad sync turned on our domain ...
And if you want the domain in office 365 you could, but check the DNS records for that domain! This is were you set were the mailserver is (MX) etc..
If you want to continuea using the OnPrem server for e-mail, simply disable Exchange Online for your users and you should be fine
