It could be a wrong password or account or pop3-server, or other connection parameters that you may set in Outlook Express.
Postoffice.worldnet.att.net doesn't look like an account, to name something. Usually that's something like firstname.lastname@example.org or email@example.com or whatever (I won't tell you mine).
And the pop3 server usually is something like pop3.att.net.
Are you sure she did configure her account settings correctly?
Hope this helps.
Trying to help a friend that is on basic AT&T worlnet service so she gets no free tech help from AT&T. She is using windows 98, outlook express 6 and IE 6. This is one single home computer accessing the net with dialup. When she is in IE and clicks to get her mail this error pops up from outlook express.
The connection to the server has failed account postoffice.worldnet.att.net server mailhost.worldnet.att.net protocol SMTP port 25 secure (SSL): no socket error 10065, error number 0x800CCC0E.
I googled socket error 10065 and this is what I found was it means no route to host but I am an AOL user so I have no clue about outlook express or IE so can someone explain to me what's going on and how I can help her fix it. I think she is not getting her mail and when we tried to send mail we got that error also so I don't think it's sending and possibly not receiving. Also wepages are loading fine but when she wants to buy something and gets to the last part of the check out, when she clicks continue she gets this page cannot be displayed and can't order anything. Only when on the last part of ordering from a website and not just one site it's every site she tried to buy from so would this be connected to the socket error?
