I think there is much more potential here. An individual can configure their LinkedIn public profile to show more or less information. LinkedIn public profiles usually give name, where they work, job title, profile picture, bio and recent posts. If the person you are chatting to has a LinkedIn profile associated with the email/UPN or it will do a search by name (like Outlook), then their public photo and other details are now available as a tab in 1:1 conversation. This requires that your tenant has the admin setting for LinkedIn integration turned on, it is enabled by default. This will begin rolling out in mid-March and expect to complete by early April.

Initially, this is limited to contacts within the tenant, but as the contact card updates are released, then this will be available for all contacts within and outside the tenant. Users will be able to see LinkedIn profiles of their colleagues in 1:1 chat, not in the contact card, but as a separate tab in the chat. Now Microsoft has announced some LinkedIn integration into Teams. Many years later we did see LinkedIn details in Outlook Contact cards, but not a great deal more. At the time there was a lot of talk about the value of integrated LinkedIn to Microsoft Office 365 and Dynamics.

Users are prompted to connect their accounts the first time they click to see someone's LinkedIn information on a profile card in Outlook, OneDrive or SharePoint Online. Microsoft bought LinkedIn way back in 2016 in an all-cash transaction valued at $26.2 billion. To see LinkedIn information in Microsoft apps and services, users must consent to connect their own Microsoft and LinkedIn accounts.
