HC10 provides support for outclass collaboration servers and provide easy ways to manage the Exchange servers in an efficient manner. 

The latest addition to the Microsoft Exchange line is the Exchange Server 2019 and it brings with it the promise of a more focused approach towards collaboration.  

Hosting Controller can be set up in single-tenant or multi-tenant configurations.

Single-tenant configurations are usually used by smaller organizations having the instance of Microsoft Exchange dedicated only to itself. Such configurations have one organizational unit and all mailboxes reside under that OU.

Multi-tenant configurations are used by service providers, and at times by large organizations, sharing the same instance of Microsoft Exchange among multiple customers. They create multiple OUs; one OU for each customer and Hosting Controller applies extra Multi-Tenant security settings that keep one customer’s data separate from the other.
