Outlook integration has also been added, and it's quite slick. The new client synchronizes its calendar with one's Outlook calendar. Scheduling a meeting in Outlook is automatically reflected in the calendar provided AIM's tab and vice versa.
But there a lot that's missing from AIM Pro, namely:
Differentiated presence Business users should be able to set different availability states for different classes of users. So they should be able to indicate that they are "away" to some users, but "available" to others.
Phone directory Darn, when will IM providers build interfaces that display contact information in the IM panel? We just need a phone number or extension. The IM window is perfect for that sort of thing. AIM Pro currently provides no facility for entering extension information or other details about the contact. What's more, within a company you'd like to pre-populate a user's IM address book with the names, title, and phone numbers of people in the company or the group.
