We are preparing to migrate on-premise Exchange 2007 to Office365/Exchange Online.
We will use Azure AD Connect to sync to O365.
Although we are one forest/one domain, we actually are a "local" domain, but Exchange is configured to accept both our "local" and our "external" domain name.
Our users have multiple aliases, with the published "Set as Reply" as the "external" domain.
How does Azure AD Connect handle this and does something special have to be done?
Thanks,
Mike
