Engst When it comes to calendaring, the two major technologies are CalDAV, which BusyCal has long supported, and Microsoft Exchange, which makes it debut in the just-released [1]BusyCal 2.5. This is a big deal, since it means that BusyCal can now be used to [2]interact with corporate Exchange calendars as a full-fledged calendaring citizen, surpassing Apple's Calendar app in numerous ways and providing an alternative to Outlook itself. Notably, BusyCal 2.5 offers more-granular calendar sharing privileges, public calendars, push syncing, Outlook categories, shared tasks, repeating tasks, shared-calendar notifications, rich text, and graphics. Other new features include an Availability panel for scheduling meetings using either Exchange or CalDAV, and 'regenerating' To Do items that return to your calendar automatically some time after completion.

BusyCal 2.5 is available as a free 30-day trial from the BusyMac site, but the only way to purchase the app is through the [4]Mac App Store.
