After a resource calendar has been shared with you, you can view it as follows:
As a user (not an administrator), access your calendar.
Click the down arrow by Other calendars and then select Browse Interesting Calendars.
Click the More tab.
Click Resources for <your domain>.
Find the resource you want to add and click Subscribe.
The resource will now appear on your Other calendars list, where you can view the events.
Note that if you follow these steps as an administrator, the resource is added to your My calendars list instead of your Other calendars list.
