When I go to Outlook.com email settings I am trying to add a send-and-receive account.  Microsoft account uses my att email as the primary account but show it as a send only.  Keeps telling me to make sure email address and pw are correct and they are.  It then tells me to try advanced settings.  the incoming shows inbound.att.net Port 995 and outgoing shows outbound.att.net Port 465.  Then it tells me it can't sign into POP3 server and to check email address and PW which are still correct.

My windows mail is set as incoming with imap.mail.yahoo.com port 993 and outgoing with smtp.mail.yahoo.com port 465 and works beautifully. Outlook won't allow a port 993 for incoming mail when I try to change Outlook settings.

If anybody can help, would really appreciate it.  I have had this computer with Win8 for almost a year and have yet to get either Outlook to work properly.  Thought using Outlook might solve another problem I keep having with Win Mail for another account.  Have really had it with both Win Mail and Outlook.  My phone handles all 3 of my email accounts without a hitch. Microsoft has stepped on my last nerve.
