I have 5 Mac users and 4 of them have no issue but 1 of them have issue receiving mail in inbox.  if he send a mail to himself I shows in sent folder but never shows in inbox.  Verified accessing account with OWA and there is no issue.  We are on Exchange 2013 SP1. The account works fine on windows machine.  I tried moving the mailbox to a different Database but no luck.  I can create a new users account and add it to outlook profile and it works fine.  Thanks so much
