It's remarkable easy to add Exchange Calendar to your SharePoint calendar as a data source. Select required Exchange version and URL of installed Exchange Server (see the picture above). If Microsoft Exchange Server is installed on another domain, you should enter login and password (it can be login and password of a user whose Exchange calendar you need to display) for connection to Exchange Server. That's all you have to do in order to overlay both calendars. Now you can change events of Exchange calendar right from SharePoint.
