I have a ZIMBRA instance running on Amazon EC2. I used the available AMI, which seems to be a little bit old.

I got it all sorted out, Zimbra works, incoming/outgoing mail is fine. Zimbra Client on Mac works as well. iCal syncing, too.

Now I have several questions:

1. I assume it is the OpenSource edition, right?
2. I am using the AMI to evaluate Zimbra as Exchange alternative for our hosted Exchange solution. But unfortunately, I read that I need the network edition to use the Outlook connector. Right? Any way around this?
3. The iSync connector, which I found somewhere online, also reported that I need a license and should contact my admin. I could not finish configuration of my account.

How can i solve these issues to properly test the ZIMBRA functionality including Outlook/iSync etc.
