Hello everyone,
My company develop Zimbra in 650 accounts, with mobile module, and I deploy it to the my clients (2-10 person companies).
It's works well. After one week I can be very surprised - is the best open source collaboration server.
Due the deploying I didn't saw a manual to the Zimbra and Azure. So I will do that in the current week.

If anyone have a question please write :-)))
