Evening All Was wondering if somebody could help me out, got a bit of a problem with Outlook 2010, i have installed Office on a 2008 R2 Terminal Server box, and im logging in as a user (To Test) and opening Outlook to check my email, now when i open it i have two problems. First problem is, Outlook does its auto discovery bit, and finds my users name then errors with "An Unknown error occurred, error code:0x80070057. If i ok this and configure the account manually by typing in the name of my mail server it connects and works fine, mail server is Exchange 2003, is their any compatibility issues does anyone know? Second problem is, once you open Outlook as the user i get a "Help protect and improve microsoft office" setting prompt, asking me to choose "Recommended Settings" or "Install Updates Only" just wondering does anyone know if group policy can get rid or choose a option for the user Thanks Phil
