My quest for Exchange to iPhone calendar synching without Outlook continues and the most promising find yet is Groupcal from Snerdware. The application isn’t cheap at $54.95 a license, but if works as promised, I’d consider the out-of-pocket expense. Groupcal is geared for enterprises that run an Exchange server, but have Apple iCal clients. I downloaded the trial last night and got Groupcal to see my hosted Exchange server but alas: it currently only supports Exchange Server 2000 and 2003. My provider has recently migrated to Exchange 2007 which Groupcal noticed and informed me that I’m outta luck.
Others looking for a pure Mac iCal or iPhone solution might consider the free trial. When combined with Spanning Sync or another third party app, Groupcal might get appointments from Exchange into Google Calendar as well. Meanwhile, it’s back to the drawing board for me unless there are more rumors floating that Apple is licensing ActiveSync from Microsoft.
