Managed users

[Audra Bonacki]

Hi, I set up a new user the same as I have all other users but for some reason they've been set up as a Managed Account and they are not able to verify their email for some reason. I've tried deleting and deactivating them to try and re-add them but its not allowing that. There's no apps associated with their account so I'm not sure why this got set up like this. How do I remove the Managed account status?
