The problem is with an offline logon to the computer using a smart card Outlook is not able to connect to the Exchange server even once the network is available (see steps below)
a) Logon with smart card when the computer is not connected to the network
b) Then connect the computer to the network
c) Open MS outlook and it tries communicating with the Exchange server but fails (smart card appears busy when outlook attempts to communicate with the exchange server)
d) The windows event log shows Smart Card Logon error( Event ID 17) : "An error occurred while decrypting a message: key not valid for use in specified state"
Are you aware if there are any additional steps required after an offline logon using smart card to authenticate with the domain once the network is available.
