Sorry, I am a bit confused. I am currently using Zentyal 3.2, I am not using Zarafa, and I don't have a subscription. I've read all I can find on the subject, but I can't find anywhere that explains the new OpenChange module fully, especially in regards to Zarafa. Rather than set up a test box and install 3.3 to find out, can somebody tell me if OpenChange essentially replaces Zarafa? That's what seems to be implied, and also that you can have unlimited OpenChange users without a subscription.
Thanks!
