Change maximum number of mailboxes

[w0uter]

Hi,

I try to change the maximum number of mailboxes for a domain but it dont work.
I go to Domains -> domainname -> Limits then i see that the number of maximum number of mailboxes is 5. I change it to 10 en click ok. Pelsk says then: Some fields are empty or contain an improper value. And make a red line by maximum number of mailboxes. Whit the follow text there under: Mailboxes: requested - 10, maximum available - 5.

How can i fix that the domain has 10 mailboxes available ?
