Request your demo license key

Install your demo license key

While the software will run without a license, you’ll need a valid license with enough users to create new user accounts. On a fresh installation, this means you will need the license to be installed before the first mailbox can be created. We will send you your test key as soon as possible.

Please follow the complete guide to apply all steps required for your individual installation.
