First off we have covered this(many times), please search. We do not have plans today to sell the connector stand-alone. In the future we may revisit that decision, and we'll be sure to announce it. So there's no need to post/re-post every couple weeks.
Let me elaborate just a little. The Network Edition is not just about Outlook connectors. It's about supporting the future development of Zimbra. It's about the support here on the community forums. It's about all the magic in the server which handles, tags, folders, conversations and that lightning fast search. It's about the countless hours that were spent in a JavaScript debugger getting all 130,000+ lines of JavaScript aligned for that WOW factor you've all experienced. It's about native HSM, hot backup, single mailbox restore, delegated domain admin, attachment indexing, clustering, and yes it's about Outlook sync. It's also about all the new features folks here are hard at work on. In part that's why it's called a Network. It's more than just support or some additional features, it's about the greater good that being part of a *Network* can achieve.
