OS is Windows XP; I had Outlook 2000, which was never used because we used AOL. I finally set up Outlook, using the incoming mail server of "mail.adelphia.net" and smtp of "smtp.adelphia.net". Everything worked fine.
Then Adelphia became Roadrunner and I was told to change my incoming mail server to "pop-server.roadrunner.com" and smtp to "smtp-server.roadrunner.com". Now I can neither send OR receive, getting the error message that "none of the authentication methods supported by this client are supported by your server". The old Adelphia settings won't work either. Roadrunner tells me that all my settings are correct and that it's a Microsoft problem. Does anybody out there know of issues with Outlook 2007 and Roadrunner?
