Hi,
I am performing a migration to a hybrid exchange deployment.
I have looked on the deployment assistant for autodiscover dns information but it just says I need autodiscover.domain.com externally pointing to my on premise CAS which I already have from my current deployment.
My question is... If a user mailbox gets moved to office 365 how does autodiscover work to redirect them to the cloud service for their URL's?
Can someone give me a high level description for internal and external outlook users?
i.e. external user: connect to cas using public autodiscover.domain.com A record, on premise CAS provides alternative autodiscover URL??
