"Source User is locked"

I’m an admin trying to transfer files from one user who has left our organization to her supervisor… however… I am getting an error "Source User is locked" with the API or “...is in another operation” when attempting to move files or change the folder owner in Box -- it’s been several days and it just never changes. 

I’ve tried several things and tried waiting for days -- but this is just a weird account that won’t budge.
