Microsoft Exchange Server 2019 Enterprise - Open Government

Microsoft Exchange Server 2019 Enterprise - Open Government

Microsoft Exchange Server 2019 is available in two server editions: Standard Edition and Enterprise Edition. Enterprise Edition can scale to 100 mounted databases per server; Standard Edition is limited to 5 mounted databases per server. A mounted database is a database that is in use. A mounted database can be an active mailbox database that is mounted for use by clients, or a passive mailbox database that is mounted in recovery for log replication and replay. While you can create more databases than the limits described above, you can only mount the maximum number specified above. The recovery database does not count towards this limit.

These licensing editions are defined by a product key. When you enter a valid license product key, the supported edition for the server is established. Product keys can be used for the same edition key swaps and upgrades only; they can't be used for downgrades. You can use a valid product key to move from the evaluation version (Trial Edition) of Exchange 2019 to either Standard Edition or Enterprise Edition. You can also use a valid product key to move from Standard Edition to Enterprise Edition.

No loss of functionality will occur when the Trial Edition expires, so you can maintain lab, demo, training, and other non-production environments beyond 120 days without having to reinstall the Trial Edition of Exchange 2019.

As mentioned earlier, you can't use product keys to downgrade from Enterprise Edition to Standard Edition, nor can you use them to revert to the Trial Edition. These types of downgrades can only be done by uninstalling Exchange 2019, reinstalling Exchange 2019, and entering the correct product key.

Microsoft Exchange 2019 is the latest version of this popular email and calendaring software and includes many features to make productivity a safe and secure endeavor. This Enterprise version expands on the features found in the standard version, most notably with the ability to scale to 100 mounted databases per server. The standard version is limited to five databases per server. Exchange 2019 includes data loss prevention with more sensitive information types as well as enhanced auditing for better reporting and easier integration with third-party apps. The email inbox in this version is more personalized and has more intelligent features and faster search capabilities to allow your employees to get more done. Exchange 2019 Enterprise can be used on mobile phones, tablets, desktops and the web and this server powers the latest Outlook. Note that this is an Open License and is designed for businesses with between two and 250 computers. Open licenses are perpetual licenses and the program term is two years.
