Using the Exchange Server Deployment Assistant
5. The next three questions are specific to your desired deployment model. Answer
them accordingly. For this exercise, we have chosen to use on-premises credentials,
also known as single sign-on (SSO), and to route email to and from external
recipients through Exchange Online. We will not be using an Edge Transport server to
route emails between Exchange Online and our on-premises Exchange environment.

INSIDE OUT Why did we answer this way?
The reason we chose to answer the five questions the way we did and selected this
scenario for this exercise is because it is the most popular hybrid mailbox scenario, in our
experience. Most customers we encounter would like to phase the deployment, which
means some mailboxes remain on premises and others are in Exchange Online. Secondly,
they do not want to cause degradation in experience for the users whose mailboxes
are moved to Exchange Online; therefore, SSO is a non-negotiable requirement. Finally,
most customers also want to offload the Hub Transport server role so they gain
better fault tolerance for Internet email transport and at the same time take advantage
of offloading the email protection workload because Forefront Online Protection for
Exchange (FOPE)/ Exchange Online Protection (EOP) is integrated with Exchange Online.
