The license defines the number of mailboxes that can be created in Kerio Connect. The active mailboxes occupy the user's license limit. Once the limit is reached, Kerio Connect restricts administrators from creating new mailboxes. You may receive "Total number of user mailboxes authorized by the license has been exceeded" warning in Dashboard.
You cannot add more users warning message will be displayed during the account creation process.
In such cases, the user mailboxes can be deleted to free up the license.
Note: the current number refers to the number of accounts in a particular selected domain. Kerio Connect can detect the overall number of users created for all domains.
How licensing Works in Kerio Connect?
Licenses are counted by the number of users. The number of users means the number of mailboxes or accounts that are:
- Created and enabled in Kerio Connect.
- Mapped from a directory service. All users created in this database are count as licenses.
- Imported from a domain.
The following don't count as licenses:
- Disabled accounts.
- Mailing lists.
Internal built-in administrator account.
Note: any accounts created with the "Admin" privilege will still take up a license as these are different from the "Internal built-in Admin" account.
If you want to increase the number of users allowed by your license, visit the Kerio Connect website.
Users mapped from a directory service
When you map users from a directory service, all users created in the directory service are imported to Kerio Connect. The total number of users in Kerio Connect may thus exceed the number allowed by your license.
Once the number of users who connect to Kerio Connect (i.e. create a mailbox) exceeds the number of users from your license, no other users are allowed to connect to their accounts.
Checking the number of users in your license
The Kerio Connect Administration interface displays information on the number of users you have and the number of licenses you hold.
Go to Status > Dashboard and view the License Details tile.
You can remove inactive users to make space for new users in your license:
- Go to the Users section.
- Click the arrow next to a column name and select Columns > Last Login.
- Sort users based on the Last Login and accordingly remove users who do not use Kerio Connect.
Note: it's recommended to reboot the Kerio Connect server to apply user deletion changes.
