I've got Office 365 Home Edition. I'm running Windows 10 Professional. With the Windows 10 fall 2018 update, the ability to have contacts on the taskbar was made available, more than usual. This is great, I love it! I've put all my family members there.
Recently in the lower right "corner" of the contacts for my son and daughter, there's a number. For my son, the number is 2, it is in a small black circle. For my daughter its a 1, in a small black circle.
What is the meaning of that number?
