Introduction to publishing Internet Calendars

Internet Calendars are calendars that are shared through the Internet. Internet Calendars are based upon a global Internet standard that allows calendar information to be exchanged regardless of the application that is used to create or view the information. Internet Calendars use the iCalendar format and the .ics file name extension.

Internet Calendars are shared either by sharing one-time static calendars, known as Calendar Snapshots, or by publishing calendars to a special Web server designed to host calendars in the iCalendar format. The benefit of the latter is that as you make changes to the calendar in Microsoft Office Outlook 2007, the changes are replicated to the Web server. This allows those who use an Internet Calendar Subscription to get the latest information automatically.

This article describes the process for publishing Internet Calendars. If you want more information about Calendar Snapshots, see Introduction to Internet Calendars. More information about all the different ways to share calendars in Office Outlook 2007 is available in Share your calendar information.

Why publish Internet Calendars?

It is useful to publish Internet Calendars if you want to share calendars and availability information with others, especially when neither you nor the viewers of the calendar information use a software application such as Microsoft Exchange. Publishing Internet Calendars is not proprietary to any one application or operating system.

For example, you can publish your soccer team's practice schedule. Each player can subscribe to the published calendar and see any updates that you make to the calendar. It does not matter whether the other people choose to view the Internet Calendar Subscription in a Web browser, Office Outlook 2007, or another application.

Office Outlook 2007 offers you two primary ways to publish Internet Calendars:

  • Publish to Microsoft Office Online
  • Publish to a Web server

Publish to Microsoft Office Online

You can create a new Internet Calendar from within Office Outlook 2007 easily and publish it to Office Online. By using the security provided by your Microsoft Windows Live ID credentials, you can grant other people access to this calendar so that everyone has the latest information.

You can publish Office Outlook 2007 calendars to Office Online and control who can access them. Office Online does not require the publisher or a user of the calendar to use an Exchange account. For more information, see Share your calendar on Office Online or visit the Office Online Internet Calendar Publishing Service.

Publish to a Web server

Sharing calendars is not restricted to Office Online. If you have access to a Web server that supports the WebDAV protocol, you can share calendars with others. However, when you use this method, you can establish access restrictions only through server and folder permissions, and you may require the assistance of the server administrator to set up and maintain the access restrictions.

For more information, see Share your calendar on a Web server.

What is WebDAV?

World Wide Web Distributed Authoring and Versioning (WebDAV) is a protocol that the Web server to which you are publishing a calendar must support . WebDAV enables you to create and modify documents on a Web server and is an extension of the HTTP protocol that is used by Web browsers to view Web pages and other content.

Not all Web servers support WebDAV. Even if you can use File Transfer Protocol (FTP) (FTP: A communication protocol that makes it possible for a user to transfer files between remote locations on a network. This protocol also allows users to use FTP commands, such as listing files and folders, to work with files on a remote location.) or directly save files to a universal naming convention (UNC) (universal naming convention (UNC): A naming convention for files that provides a machine-independent means of locating the file. Rather than specifying a drive letter and path, a UNC name uses the syntax \\server\share\path\filename.) path such as \\server\teamdocuments, this does not indicate that WebDAV is available. Your server administrator or Internet service provider (ISP) (ISP: A business that provides access to the Internet for such things as electronic mail, chat rooms, or use of the World Wide Web. Some ISPs are multinational, offering access in many locations, while others are limited to a specific region.) can tell you if WebDAV is supported on the server that you want to use.
