I am adding a user to Box Relay or a similar app where I need to add a user. I get an Error that says "Specified login(s) are deactivated or otherwise invalid. Please remove them from the list before saving."

Now I have to somehow know what user was deactivated???? If there is an error, tell me what user is having the issue or do not give me the error. When the user is removed, it will go away.

Very frustrating to have to go through a list of random users to add a user.
