Is it possible to set a mail-box quota for all mailboxes in a service-plan? For example max-mailboxspace for service-plan = 25GB now the customer can create 5 mailboxes with 5GB quota or a single mailbox with 25GB quota and so on is this possible? as i know its not? would be a cool feature i think. till now you can set a quota per mailbox but if you give your user the abbillity to create 20 mailboxes he is able to create 20 mailboxes with max-quota. a way to limit mailbox creation by used mailbox-quota would be great.
