BusyCal adds Exchange support

BusyCal has added Exchange support for BusyCal 2.5 ($30), an update to the calendar alternative to OS X's Calendar. This update focuses on Microsoft Exchange Server and Office 365, enabling BusyCal to access Exchange and adding an Availability Panel for scheduling Exchange and CalDAV meetings. It also adds the ability to regenerate to-dos.

With the new version, changes are synced immediately between Exchange and BusyCal using push. When you share a calendar with multiple users, you can assign different access privileges to different users. These include read-only, read/write, delegate, and Free/Busy, which let you view the availability of attendees when scheduling meetings.

BusyCal 2.5 can sync tasks with Exchange and share them with other BusyCal users. The update also supports repeating tasks. BusyCal can create Notifications when when changes are made on shared calendars.

BusyCal says it has several features that the company says that aren't found in OS X Calendar or Outlook for Mac:

BusyCal's unique features include customizable calendar views, scrolling Month and Week views, an integrated Info Panel for quickly viewing and editing events, integrated To Dos that display in the calendar and carry-forward until completed, custom font sizes and styles, graphics, live weather feeds and moon phases, and a menu bar app for quick access to the current day's events and weather.

BusyCal supports iCloud, Exchange, Google Calendar, and other CalDAV servers, enabling you to sync and share your calendars with other Macs running BusyCal or the built-in Calendar app on OS X, as well as iPhones and iPads running the built-in Calendar app on iOS.

BusyCal 2.5 requires OS X 10.8 Mountain Lion.
