Evaluation Limitation 25 mailbox -question

Hi

We're evaluating the Exchange Reporter PLUS in our LAB
Currently managed by our test is 25 mailbox

What will happened in my LAB if mailbox user is more than 25 ?
My I know if the "Exchange Reporter PLUS " will stop the reporting or will collect data randomly in different mailbox?

Please advise what is behavior if the mailbox is user is more than 25 ? since we're using in the ALB is evaluation only
