Are you aware of iCal server? This appears to be Apple's attempt to tie undermine Outlook / Exchange's killer features. I expect it to be pretty good. Are ALL the clients Macs? I think this would probably go quite well if that's the case. I see the big stumbling block to be if you currently have Outlook clients on Windows - I think they would quite reasonably be reluctant to switch to Thunderbird or whatever. You ask about open projects - Apple are releasing the source to iCal server under an OSS license. I think the idea being to spur wider adoption & encourage 3rd-party clients - I anticipate a bunch for Linux and a handful for Windows and that one or more of the latter might be quite decent as an Outlook-replacement in a couple of years time. You'll have to cost-benefit for yourself whether you wait and grab OS X server at next release and take advantage of Apple's sweet configuration utilities or stitch the services together now yourself under Lunix; one could imagine that the latter could easily increase the daily workload of a busy system administrator by a significant amount. > Is anyone using iPhone on an enterprise level yet with OSX server? This is surely only necessary if you're the IT department to an enterprise which only employs Apple fanboys. I'd ask first, "what do I need to achieve with mobile phone integration?" and then consider client software; IMO the iPhone may not be the best choice. Stroller.
