Dear All,
I have on-premise Exchange with one domain like ABC.com running and sync with office 365 without any issue. But I have few more domain with different smtp like xyz.com, zzz.com, and so on in same forest, each of there user mailbox are created in there own
OU. How do i sync second smtp domain to office 365.
Do i have to convert each domain to federated, verified in 365, and run the command set-hybrid to popluate them while configuring hybrid set from within ECP.
