When I tried to set up a second email account (peters-up40@t-online.de), I received the following error message: "login to the server failed. The configuration, username or password may not be correct." The new address is correct, it was confirmed to me by Telekom. The PW is the same as in my first email address. What did I do wrong? Regards, Uwe
