Microsoft Exchange Server 2013 Enterprise Volume licence
Microsoft Exchange Server 2013 Enterprise is the optimal solution for efficient e-mail communication. Exchange Server delivers more control and security, regardless of whether you are using your server for in-house operation, as an online service in the Microsoft Cloud or as a hybrid solution.
The Enterprise Edition is different from the Standard Edition due to the number of mailbox databases. The Enterprise Edition provides you with access to up to 100 databases, making it optimal for SME organizations.
In addition to the Microsoft Exchange Server 2013 standard license, you'll also need CALs (Client Access Licenses) for client-based access. You can acquire device CALs here in the shop.
