It may be because he is in new surroundings. Max is like that and I am working on it. He was completely potty trained before but when he came to my house he thought it was ok to poo in the house (and mark before neutering), and he still does. Make sure she is praising him when he goes outside and ignoring the inside accidents. She needs to limit his freedom to where she can see him at all times or else he goes in the crate/exercise pen. Also he should be on a schedule of when to go out. She needs to be persistent and not give up.
