In Microsoft Office Outlook 2007, you can customize Internet Calendar features. Users can send and receive Internet Calendar files as well as subscribe to third-party calendars. You can set up subscriptions for a specific project and then make the calendar available on an internal server. For example, you could set up subscriptions to a calendar that shows project deadlines. Users can set up subscriptions as well. For example, a user might send an Internet Calendar soccer schedule to team parents. Or a user might sign up for an Internet Calendar subscription for a professional baseball team schedule, where the schedule is updated on the team's Web site and sent to the subscriber.
This topic is for Outlook administrators. To customize Internet Calendar options on your computer, see Sharing your calendar.
You can lock down the settings to customize Internet Calendar features by using the Outlook Group Policy template (Outlk12.adm). Or you can configure default settings by using the Office Customization Tool (OCT), in which case users can change the settings. The OCT settings are in corresponding locations on the Modify user settings page of the OCT.
The Outlook template and other ADM files can be downloaded from 2007 Office System Administrative Templates (ADM) on the Microsoft Download Center.

More information about configuring Internet Calendars
More information about configuration options is included in the following sections.
Disabling Internet Calendar subscriptions
You can disable Internet Calendar subscriptions in Office Outlook 2007 if, for example, you are concerned about bandwidth usage and want to delay introducing Internet Calendar subscriptions. By default, Internet Calendar subscriptions are enabled.
When you disable Internet Calendar subscriptions, the Internet Calendar heading does not appear in the Calendar’s folder hierarchy, and the Internet Calendar tab does not appear in the Outlook Account Manager dialog box.
Providing Internet Calendar subscriptions to users
You can deploy Internet Calendar subscriptions as default subscriptions that users can change or delete. Or you can lock down Internet Calendar subscriptions so that users cannot make changes or remove them. Users can add new Internet Calendar subscriptions, however.
By default, there are no Internet Calendar subscriptions, but users can add and remove them.
Synchronization interval for Internet Calendars
Outlook sets the synchronization interval so that each Internet Calendar subscription is updated at the publisher's recommended interval. Users can override the default interval unless you disallow that option. However, if users set the update frequency to a short interval, it can cause performance problems.
By enabling the option in Group Policy, you can enforce the use of the publisher's update intervals, so users cannot change the intervals. This setting is used for all Internet Calendar subscriptions; you cannot set this option differently for different subscriptions.
