Hey Guys, Upgraded this morning to Mountain Lion. Now no exchange mail is working?? I can receive now mails but they do not stay there for long, they vanish somewhere..... and it will not sync any previous emails at all? Icloud works but that is it. Also in the Console every 2 seconds I am getting tonnes! of these : 27/07/2012 14:10:43.627 sandboxd: () Mail(397) deny file-read-data /Library/Preferences/com.apple.mail.plist Any ideas?
