Hi @Serrnovik ,
Does this problem happen on all clients or just one client?
In OWA, does the LinkedIn tab appear on the profile card? If so, please check the client settings:
Select File > Options > In the General section, under LinkedIn Features, select the check box Show LinkedIn features in my Office applications > select OK to save your changes.
If the users in the organization are not displayed, use Group Policy to enable LinkedIn account connections.
If you have any further updates on this issue, please feel free to post back.
