I've been having some problems with Entourage 2004, I've never had problems with Entourage until yesterday. Today after restarting, Entourage will not open. It says the database is corrupted, and I have to rebuild it. But I can not rebuild - the Entourage database runs on an error as soon as it starts and says it has an I/O error. What is Entourage Database error I/O ?? How do I get rid of this ???
