Publishing full calendar information
One limitation of using the Internet Free/Busy service is that you cannot see the full details of an individual's appointment, nor can you effectively see more than two weeks of free/busy time at a glance within the meeting request. Outlook has a nifty feature that can create a Web page for you automatically which contains a full calendar view for the dates you specify, along with the full appointment details.
To publish your calendar, click Save as Web Page on the File menu while in your Calendar view. In the dialog box, you can specify the date range and a background graphic, amongst other things. After you choose a file location, your Calendar Web page is good to go! Just publish it to your ISP's Web server or a shared location on your network, and your schedule is readily available for viewing by anyone with access. However, this information is read-only to others and does not get automatically updated when your appointments change. You'll need to republish your calendar periodically whenever you make modifications.
Note Publishing your calendar requires that you have the Web Publishing Wizard installed. You can download the wizard from the Microsoft Download Center.
