Introduction
In Azure Boards, while working with Sprints we define capacity of the team. During the creation of a new sprint, in the capacity tab you can add your existing project team members if you do not see your team members listed.
In order to add all team members, click on the 3 dots(...) menu and select “Add all team members” option which adds Team members which are defined from Project settings > Teams > Team members of your Sprint.

Note: This action retrieves maximum of 100 member from your Sprint team and if you want add more users use "Add user" menu option.
How to find team members
While creating the sprint we select a team (To get team option you have to create New Sprint from Sprints directory) and for that team you can find members from Project settings > Teams > Team members of your Sprint. Refer below figures.
