Our management team all use iPhones with the built-in iOS calendar app. We're looking into getting Microsoft Exchange for everyone here, but that'll take us some weeks to plan and roll-out across the enterprise.

In the meantime, I need to provide something so group meeting availability can be determined from those calendars. Google Calendar would be ideal ("find a time") if I could find a way to link to/export the iCloud calendars, but Apple don't seem to want to do that. I could ask the management team to recreate their events for the next few weeks in individual Google Calendars, but they won't want to do that and it's wasteful rekeying of data.

Any suggestions you can provide will be gratefully received.
