Default Exchange activesync service not working after upgrade to. 4.2.2

I upgraded my GN8.0 to 4.2.2 using kies and since then am note able to get my emails both my corporate and personal email (exchange and hotmail) I keep getting the message exchange service is not working. I have removed the accounts and tried to setup again but not allowing me to even setup new account. I have done soft and factory reset but still issue not solved. Please has any one experienced this and how can it be resolved. I really need my emails on the go.
Thank you
