Automatic inbount Mail to Case

Hello,

I am new to the CRM, I have tested inbound and outbound emails conf. and successfully. In the inbound email, the support email has a check mark on “Automatically in case”. Nevertheless, the CMS does not create an Automatic email response nor does it create a a case.

Since we need this mandatory for internal purposes, I need a quick solution.

Maybe someone can answer me how to upgrade from version 7xx to 8xx.
