Troopr may be able to map up to 100% of the accounts depending on your Jira setup. Mapped accounts will show up as unverified in the "Jira User mapping" page of Troopr web app. You can see the list of mapped accounts by clicking on "Map team members" link in Home tab of "Troopr Assistant" app in the footer section. For the accounts that Troopr is not able to map, you can use the manually map them by clicking "New Mapping" (as described in above section).
