Hello i just upgraded my Free version of 3cx ver 15 to 15.5 yesterday (11/08/2017) and now i can't change any of the Setting for the email server. The Setting are all Grayed out and wont allow me to change anything. I have a payed license of 3cx ver.15 that i want to upgrade to 15.5 but i have to be able to get the email working. Am i missing something with licensing that wont allow me to use an external SMTP server??
