We would like a toolbar developed for Microsoft Outlook 2003/2007/2010 that allows three functions:
a) Click-to-call a contact from the outlook address book
b) Click-to-call the sender of an email when in pre-view mode
c) Visualize presence of a contact or presence of the sender of an email
Click-to-call capability and presence based on email address is delivered over a REST interface from an external system. The toolbar has to allow the user to configure the external system (host name, credentials).
The user experience should resemble the experience a user gets from using Microsoft OCS with Outlook.
