We're using an Exchange Server and Outlook in a private context. Since Exchange is getting more and more of a monster to maintain and is basically the only thing running on a Windows VM Server, I'm looking for an alternative with the following properties:
- Server based back-end that that can be installed / deployed on my machine and is not dependent on any third party services (e.g. Google Calendar).
- (Easy) import of existing Outlook calendars, either via some feature of Exchange or by ex- and importing from Outlook.
- Roughly the basic features of the Outlook calendar (categorizations, series, etc)
- Synchronization with the iPhone over wireless without a hitch (e.g. double or missing entries)
