Can I ask how exchange server is liscenced? What kinds of liscence are involved, i.e. are there any specifics on how many mailboxes you store in your mailbox databases? Or the types of server roles you use in your environment? We need to check our compliance to software liscensing and would be interested to know how you would go about it for your exchange environment.. having never purchased software liscences for server apps like exchange, in what format does the liscence come? Can you obtain liscence keys via any sort of shell commands? And do they last forever, or are they annual type liscences, with renewals involved?
