Activation failure

In the case activation of ESET Mail Security was not successful, possible scenarios are:

•License Key already in use

•Invalid License Key—product activation form error

•Missing or invalid information must be addressed

•Communication with the activation database failed—try again in 15 minutes

•Connection to ESET activation servers is unavailable or disabled

Ensure you entered the proper License Key or attached an Offline License and attempt to activate again.

If you are unable to activate, see the activation troubleshooting wizard.
