To access a list of users, navigate to Settings > Org > Users. There is a search box at the top. If the desired user is not visible in the list of users or when searched, they may be archived or suspended. Use the boxes on the top right to select the user statuses that are visible.
"Email Already in Use" When Creating a New User
If you try to create a new user and get an "email already in use" error, but no active, archived, or suspended user with that email appears in the org user list, the email may belong to a previously deleted account. Deleted accounts still reserve their email address in Enerflo.
Fix: Contact Support to check for and restore the deleted account under the correct company. Once restored, update its roles and permissions rather than trying to create a new user from scratch.
