I am gettign the folliowing message when using the 340 via OWA on Exchange 2010:
Your session has timed out. To protect your account from unauthorized access, the connection to your mailbox is closed after a period of inactivity. Please re-enter your user name and password.
This is only since i have re-set them up due to moing all exchange servers and NLB to new network.
Access to OWA does work as if i browse to one of the CAS servers instead of the VIP address it works fine.
