Entourage 2008 -> ActiveSync -> Zimbra
Since it seems that using CalDAV to sync calendars between Zimbra and Entourage 2008 is a non-starter (due to Microsoft), has anyone examined to possibility of using the Exchange Server Impersonation features of Zimbra server to make Entourage think it's connecting to an Exchange server instead?
I'm assuming that Entourage uses ActiveSync to communicate with an Exchange server the way that Windows Mobile/IPhone devices do. If that is, in fact, the case, what would it take to get Entourage to use the same conduit? If not, has any thought been given to enhancing the Zimbra backend until such a connection is possible?
Microsoft Entourage EWS Public Beta
Take a look at this:
It was announced during MacWorld.
Granted, this is just a beta at this time, and as such there are obviously no guarantees it will work with Zimbra at all. But the prospects are good. However, over time, my guess is that it probably will. I haven't tested it myself yet, but will as soon as I have time.
Report back if you try it.
