okay, have look, but can not find.
This is what I do when sending emails using outlook 2016.
I search for the contacts, I pick the contact, then pick "Email" (or right click and select create email). Since I have 3 email address for that contact, the email, send "to:" insert all 3 email address. I want the option to pick only one of the emails, just like if you were going call the person.

how do I fix this.

Thanks
