I have a on the road salesmen that continues to be locked out by AD. This just may be something I am not familiar with but from his laptop and a internet connection outside of our network he can send and recieve email with the local outlook not being in the office connected to our network??? He says he logs in remotely using RDP to our terminal server and closes the Remote session. From there he can open outlook locally on his laptop and send/receive email. His account continues to get locked out now even when he only uses the terminal server. First I didnt know this could be done with Outlook and would like to know more about it. Second there doesnt appear to be any consistency of when he gets locked out. He has had to change his password within our AD domain when logged in RDP to terminal server. Password cannot be changed on his laptop until he is back in the office connected to our domain. Is there some sort of false authentication going on here in the background with the local outlook using the old password from the laptop. Any thoughts would be appreciated! Oh outlook is 2010 on his Laptop. 2003 on the terminal server. This may not have anything to do with his problems but no one else have used outlook this way and there arent any complaints from other users being locked out.
