Renaming domains in Kerio Connect

In Kerio Connect, you can rename your domain in the administration interface. Once a domain is renamed, the original name becomes an alias. This ensures that email messages sent to addresses with the original name are always delivered.

Original Server restart
domain name


The domain configuration does not change after renaming.


Any calendar events created before renaming cannot be edited or removed after the domain is renamed.


Before you start the renaming process:

Renaming domains

  1. In the administration interface, go to Configuration > Domains.
  2. Double-click the domain you want to rename.
  3. On the General tab, click Rename.
  4. Type a new name for the domain. You can cancel the renaming process before you restart the server. Click Cancel Rename in the domain's configuration.

  1. Restart the server.

Before the restart, all operations are performed using the original name. During the restart, Kerio Connect automatically replaces the original name with the new name in the configuration files.

You can restart the server in the administration interface: Go to Status > System Health and click Tasks > Restart Kerio Connect at the bottom.

Renaming distributed domains

Before you start renaming distributed domains:

  1. Disconnect all servers.
  2. Rename each domain separately (as described above).
  3. Reconnect renamed servers to a distributed domain.

Post-renaming issues

If users have email filters with addresses of users from a renamed domain, they must change the rules.

If users use Kerio Outlook Connector (Offline Edition), they must empty the cache after the domain is renamed.
