how to unregister an email address for new account creation on 3cx

[Rossrival]

Hi team, I am trying to unregister an email address for a new account so that I can manually add it on the portal

Hi @Rossrival It seems that the email address you have entered already has a portal login. Therefore, in order to add it, you would either need to log into the portal using that email address or ask whoever set up the account to do that for you. Then you can navigate to 'My account' and follow the account deletion steps. Once deleted, you should then be able to set the new customer up with the email address.
Or you could just use a different email address on the same domain to skip any issues.
