The incorrect name shows in the Connect Mini window and differs from the logged in name. For instance, if the logged in name is "John Smith," then we may see something like "Ed Roberts" showing up as the user in the Connect window.
This issue can occur when the user in question has a corrupted Live Profile.
Navigate to "live_profile.list" in the filter navigator, and search for the name showing in Connect in the "Name" column. The corrupted Live Profile should show a reference to the logged in user's name in the "Document" field.
