We have now been testing the setup for a few days, and maybe we just misunderstand the idea about the -1 (disable) email accounts when setting up a Hosting Plan.
When we setup a Hosting Plan with -1 (disabled) email accounts, and then trying do upgrade a customer to a new Hosting Plan (again with no email acounts), we get the following error: "You have more e-mail addresses in use than the new hosting plan limits."
This is of cource strange because the fact that the customer never was assigned the email accounts.
So where is the problem, annd how is it possible to make Hosting Plans without email accounts enabled?
(You probably ask why we do not want customers have email accounts. But that is very logic. We do not use the email server functions on the webserver. All email accounts are either Exchange or MailEnabled accounts!)
