Exchange Server 2019 is designed to deliver security, performance and improved administration and management capabilities that large on-premises customers expect.
- Due to improvements, you can now have 20% more users on a server.
- Better calendar management – IT admins can now cancel all meetings organized by a user
- Exchange Server 2019 requires Windows Server 2019
Exchange Server is also available as an Online Service Exchange Online or as part of Office 365, freeing you from the need to host on premises servers.
Licensing Exchange Server 2019
Exchange Server 2019 is licensed in a Server / CAL model.
With this license type, a license must be assigned for each instance of the server software that is being run. There are two server editions:
- Standard: designed for the mailbox needs of small to midsize organizations. Also appropriate for non-mailbox roles in a larger Exchange deployment. This edition supports 1 to 5 mailbox databases.
- Enterprise: designed for larger organizations that may require a greater number of mailbox databases. This edition supports 1 to 100 mailbox databases.
Client access licenses (CALs)
With this license type, a CAL is required for each user or device that accesses the server software. There are two types of CALs for Exchange, both of which work with either edition of the server:
- Standard: designed to help users be more productive from virtually any platform, browser, or mobile device, with features in Exchange Server 2019 that help your users be productive no matter where they are—while helping protect your organization's data. To enable Standard CAL features for a user, the user must be licensed with the Standard CAL.
- Enterprise: designed to allow organizations to reduce the cost and complexity of meeting compliance requirements with new integrated archiving functionality and information protection capabilities. The Enterprise CAL is sold as an add-on to the Standard CAL—to enable Enterprise CAL features, the user must be licensed with one Standard CAL plus one Enterprise CAL. The Exchange Enterprise CAL is available in two variants: with and without Services. The Enterprise CAL with Services also includes Exchange Online Protection (anti-malware and anti-spam services), plus cloud DLP in Office 365.
