What happened to the menus that were available in Office Communicator 2005?
The menus have been replaced with a user interface that makes virtually all Communicator tasks easily accessible. With Office Communicator 2007, frequently performed tasks, such as starting an instant message or placing a phone call can be accomplished from the Contact List by right-clicking a contact and selecting a menu option. You can also select the Menu button in the Communicator window to view additional menu items.
