Hybrid Exchange without AD FS SSL integration


I have been in the process of learning and setting up a hybrid solution for our current Exchange environment in order to migrate to Office 365. I was attempting to go the route of obtaining an SSL for our AD server in order to sync SSO with Microsofts AD FS as I understand it. The problem arose when our internal fqdn is the name of an outside DNS. Whoever set it up used contoso.com for internal and emaildomain.net for our Exchange domain. So I can not attempt this method. My question is, can I simply duplicate our current wildcard emaildomain.net cert and create hybrid environment in that way? Are there alternate simpler methods of creating the hybrid environment?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

SSO is NOT a requirement for Hybrid, you can happily proceed without it.

Additionally, you may also consider Exchange Server Deployment Assistant that helps you configure a hybrid deployment between your on-premises organization and Office 365, or to migrate completely to Office 365. The tool asks you a small set of simple questions and then, based on your answers, creates a customized checklist with instructions to configure your hybrid deployment: https://technet.microsoft.com/en-us/office/dn756393.aspx
