After a helpdesk email address is added to your account, it would have to be activated to start receiving tickets. To activate an email address, you would have to click on the "Send Activation Link" option, corresponding to it. This would send an email to your support email address, containing an activation link. You would have to click on this link to activate your helpdesk email address.
At times, while clicking on the link, you would receive an error saying "Activation Code Invalid". This error comes up either -
when the helpdesk email address is deleted after the activation email was triggered.
when the activation email expires because a new one was triggered.
In such cases, please make sure that the latest activation link is being used. If the issue continues, kindly write to email@example.com and one of our agents assist you further on this.
