I'm new to zimbra.
We have a customer that we would like to migrate from standard dovecot to a zimbra system.
customer's requirements is to have 10 account with outlook connector and shared addressbook/calendar, and 50 account with no outlook connector, just only pop3/imap.
Should we buy the Professional edition with 50 licenses?
In a professional edition, can I create an unlimited number of account for free or every account will need it's license?
