I have just installed Oracle Beehive, set the MX records and configured.
I created a new Exchange IMAP account in my Zimbra Desktop client on my PC and connected !!
I then create the exact same account on my Apple Mac Zimbra and connected.
But - if I move an email from inbox to some other folder on the PC client, that change is NOT seen by the client on the Mac and the other way around.
Maybe I just don't understand IMAP, but it was my expectation that the folders would be sync'ed ??
