Product activation

When installation is complete, you will be prompted to activate your product.

You can use any of the following methods to activate ESET Mail Security:

Use a purchased License Key

A unique string in the format XXXX-XXXX-XXXX-XXXX-XXXX which is used for identification of the the license owner and for activation of the license.

ESET Business Account

Use this option if you are registered and have your ESET Business Account where your ESET Mail Security license has been imported. You can also enter Security Admin credentials that you use on ESET License Administrator portal.

Offline License file

An automatically generated file that will be transferred to the ESET product to provide license information. Your offline License file is generated from the license portal and is used in environments where the application cannot connect to the licensing authority.

Click Activate later with ESET PROTECT if your computer is a member of a managed network, and your administrator will perform remote activation via ESET PROTECT. You can also use this option if you want to activate this client at a later time.

Select Help and support > Change license in the main program window to manage your license information. You will see the public license ID used to identify your product and license. Your Username, under which the computer is registered, is stored in the About section, and you can view it by right-clicking the Windows notification area icon .

After successfully activating ESET Mail Security, the main program window opens and displays your current status on the Monitoring page. Some attention may be required initially; for example, you are asked if you want to be part of ESET LiveGrid®.

The main program window also displays notifications about other items, such as system updates (Windows Updates) or detection engine updates. When everything requiring attention is resolved, the monitoring status turns green and displays the status You are protected.

You can activate your product from the main menu under Help and support > Activate Product or Monitoring status > Product is not activated.
