This is pretty exciting news. Microsoft announced that they will be rolling out an extended profile card experience across Office 365 to enhance the way you collaborate with colleagues and external contacts. There are several big improvements on top of the current user profile experience that we get on O365.
Some of the key improvements are
1) Quickly look up documents that have been shared with you, independent of how they were sent.
2) The new Organization view shows a complete picture of the highlighted user’s position in the company, including their direct reports and co-workers.
3) New profile card is integrated everywhere you see a person’s name on Office 365 without interrupting your productivity.
