How to change the suffix of my support email address?

The "mycompany" part of the email address represents the portal name that you initially signed up with. It is a one-time process, and you cannot modify this email suffix although you can update the portal name at any point in time. Nevertheless, if you are worried about displaying the wrong portal name in the support email address, it should not be a cause for concern.
