I have a user constantly getting NDR every morning within the 30 minutes of she opens her email. It happens almost every day. For the within the organization and for external addresses. she can’t even forward that to me at that time. she gets NDR. all messages has same error code. So far, I created new outlook profile, removed outlook using OffScrub and reinstalled, recreated windows profile. even swapped teh laptop. still happening.  

Anyone can suggest a remedy for this?
