Exchange hybrid licensing

Question

Hi, how is Exchange 2019 licensed in hybrid setup? If I wanna have Edge server to, does it have to be licensed with Exchange license? Or can it be on one server (without mailboxes) that we use for hybrid setup and administration of users?

Answer 1

If you are using Exch 2019, you need a license for any Exchange Servers on-prem - including Edge.

If you are using Exch 2016, you can get a free license key for the server serving the hybrid enpoint

A few years ago, we created a web site that would allow our hybrid customers to obtain what’s generally known as the “hybrid key”. This self-service site would validate your O365 tenant and after a few clicks, give you the key to license your on-premises server used for hybrid purposes. This site is no longer available for use, and we’ve come up with a better way for you to get the key. We are excited to inform you we have added a feature that will allow the Hybrid Configuration Wizard (HCW) to detect and license your designated on-premises “hybrid server”, without having to go to a separate web site or call our support team. This change is now available. You can access the HCW here.

Please note that HCW does not provide a 'hybrid key' for Exchange Server 2019. If you need a hybrid key, the latest version that it is available for is Exchange Server 2016.
