I'm assigning user licenses to the people in my org. Out of the four users I need to setup, I've assigned one license (Tallah Charles) and when I try to assign the second license (Samantha Cordero) SF says "License Limit Exceeded. All of your user licenses are currently in use by active users." I've deactivated as many as I can and I still cannot active the required users. I know the answer to this will be embarassingly simple, but does anyone have any recommendations?
