Exchange Server 2016 Editions
When you buy Exchange Server 2016 a license will be given. The license key needs to be entered after installing Exchange Server. When entering a valid product key, the supported Standard or Enterprise Edition is established.
Exchange Server Standard Edition
- Maximum of 5 mounted databases per server
- Database size limit is 1 TB (1024 GB)
Exchange Server Enterprise Edition
- Maximum of 100 mounted databases per server
- Database size limit is 16 TB (16384 GB)
Important: Exchange server Standard Edition can’t mount databases that are larger than 1 TB (1024 GB). This means that the database will automatically dismount when it reaches 1 TB.
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. 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.
You can run a DAG with both Exchange Standard and Enterprise Edition. It depends on how many mounted databases each server is going to have.
Exchange Server 2016 Trial Edition
The Exchange server will automatically run as a Trial Edition if you don’t provide a key. The Trial Edition functions just like an Exchange Standard Edition server and is helpful if you want to try out Exchange before buying. You can make use of the Trial Edition license for up to 180 days. If you want to keep using the server beyond 180 days, you’ll need to enter a product key or the Exchange admin center (EAC) will start to show reminders that you need to enter a product key to license the server.
Move from Exchange 2016 Editions
It’s possible to use a valid product key and move from Exchange 2016 Editions. Supported methods for moving Editions are:
- Trial to Standard
- Trial to Enterprise
- Standard to Enterprise
Not supported method for moving Editions are:
- Enterprise to Standard
- Enterprise to Trial
- Standard to Trial
You can’t use product keys to downgrade from Enterprise Edition to Standard or Trial Edition. Reinstall Exchange Server if you want to downgrade to these editions.
If you have less then five databases, start with Exchange Server Standard Edition. Each database has a storage capacity of 1024 GB (1 TB), giving you a maximum of 5120 GB (5 TB). How many mailboxes you put in each database is up to you, just don’t forget the database capacity limit. You can always upgrade to Exchange Server Enterprise Edition. For example, if the company is growing.
Important to know: The information in this article applies only to the Exchange server licenses. You need to buy the Client Access Licenses (CALs) separately.
