We have one outlook client that is behind a NAT (Network Address Translation) server and it can't connect to the Exchange Server. We get an error that states that the server is unreachable, do we want to open outlook offline. This same machine can logon to the domain just fine and also can access Exchange using Outlook Web Access. Any Ideas? Thanks Art

Other users can access the Exchange server. The DC is colocated with the Exchange server. (ouitside of the Nat environment). User is able to authenticate to the domain.

I have had this exact problem, it only occured when another user (not the user logged in) accessed their Exchange Web Mail from the PC and saved the username and password settings. So I simply logged onto the Exchange Webmail as the user currently logged in and saved their setting. Suddenly outlook workded fine again. wrote in message news:uzPtzRj6FHA.2364@TK2MSFTNGP12.phx.gbl... > We have one outlook client that is behind a NAT (Network Address > Translation) server and it can't connect to the Exchange Server.
