Missing "find related" feature in outlook.live.com with mouse right-click

Missing "find related" feature in outlook.live.com with mouse right-click

I have two outlook account email address removed for privacy reasons and email address removed for privacy reasons

however, I found out when I login both account via https://outlook.live.com/mail/0/, the hotmail account (I paid yearly office365 subscription) did not have "find related" feature with right mouse click. the msn account if free but has this feature, I've attached both screen shot from mouse right click and would like to get some help here.

Thanks,

Pei
