The Calendar Publishing Host creates a browse list of published calendars. However, by default, no calendars are displayed in the calendar browse list. To create a corporate calendar browse list, you need to grant rights to specific users, or at the post office or domain level, to publish to the corporate calendar browse list.
Browse to and right-click an individual user, or right-click a post office or domain where you want all users to have rights to publish to the browse list, then click.
Select, then select .
This grants the right to publish calendars to the calendar browse list.
