By using pre-owned software, companies can permanently reduce their IT costs without having to accept restrictions in terms of the software's scope of services or other disadvantages. So if you buy a used licence for Microsoft Exchange Server instead of a new one, the full scope of this groupware and e-mail transport server software is immediately available to you. However, in addition to the licence for the server, you will need a Client Access Licence (CAL) for each user that matches your server version. So if you operate a Microsoft Exchange Server 2016, an Exchange Server 2016 User CAL is required for each user; for the current version Microsoft Exchange Server 2019, a Microsoft Exchange Server 2019 User CAL is required for each user.
Exchange Server functions at a glance
Microsoft Exchange Server is a comprehensive groupware solution that can be used to manage, store and distribute emails, calendars, tasks, contacts and notes on the server. The front-end application for the Exchange Server is Microsoft Outlook, which, like the other Microsoft Office applications, is very well integrated. Microsoft Exchange Servers in turn extend the functional scope of Outlook and enable, for example, the activation of an out-of-office agent that automatically replies to incoming emails with an out-of-office message. Folders in the mailbox can also be specifically shared with other users, such as calendars or tasks.
