iCal Server 2. Push your agenda.
With iCal Server 2, it’s easy to share calendars, schedule meetings and coordinate events within a workgroup, a small business, or a large corporation. Built on open standard protocols, iCal Server integrates with leading calendaring programs. Thanks to push technology, you can notify everyone about changes instantly. And unlike other calendaring solutions, iCal Server doesn’t impose a per-user license, so you don’t have to pay for additional licenses as your business grows.
An easy schedule.
Does it sometimes seem like scheduling a meeting is harder than actually getting through the meeting? Using iCal Server, colleagues can propose and set up meetings, book conference rooms and more, quickly and easily. iCal Server is a full-featured, standards-based calendaring solution designed to make your life easier.
Think of it as a one-stop shop for setting up calendar activities. Will everyone be free for a Monday morning meeting? Search for attendee availability and see just who is booked up. Need to reserve a projector, a particular conference room, or even a car? iCal Server can take care of that as well. Once the location and the time are set, iCal Server invites the right people and lets you include information such as agendas or to-do lists with the invitation.
A new web interface and push notifications. 
iCal Server 2 includes a new web-based calendar client, allowing users to view their schedule, set up meetings and view the availability of others in their organization. The web-based calendar can be used with modern web browsers including Safari 3 and 4, Firefox 3 and Internet Explorer 7 and 8. In addition, iCal Server 2 offers push notifications, so you and your colleagues will know immediately when there’s a new invitation or a change to an existing invitation.
Real-time calendar access from
your iPhone. 
iCal Server 2 provides access to calendars from anywhere. iPhone users can securely access their calendar over the air, see calendar events, view notes and see who has accepted or declined invitations. No syncing required.
Works well with others. 
iCal Server uses open calendaring protocols for integrating with leading calendar programs, including iCal in Mac OS X and popular CalDAV clients from Mozilla, Open Source Application Foundation and others. These open standard protocols include CalDAV — a set of extensions to WebDAV — and interchange formats such as iCalendar, iMIP and iTIP. For colleagues outside your organization who don’t use iCal, you can now invite them to meetings over email. They’ll receive a message with an attachment that, when opened, will add the meeting to their calendar, whether they use a Mac or a PC.
Apple is a member of the CalConnect Consortium and is committed to open, standards-based calendaring and scheduling protocols. To further the widespread adoption and deployment of these standards, Apple has made the complete source code for iCal Server 2 available through the macosforge.org website.
