Can’t find my message

I was told in the Windows Phone Forum to move my question to the Outlook.com forum but I have not been answered here and can't find my post. What I want is help in how to set up contact and calendar sync. Facts:  Nokia 925, AT&T. Windows 8 PC. Existing account on Cox.net successfully sending emails to PC & phone. On phone, Outlook.com has been renamed Microsoft account (******@Cox.net). Clicking this, I am told that the name of the account is 'Hotmail' (which I have never used in the past)  My primary mail account is listed as: Cox - but has no contact/calendar options. I have option to add an account of the types: Outlook.com, Exchange, Office 365. I am scared to touch anything because the last time I tried to set up an account I was forced to go to AT&T store and reset all back to factory defaults. Should I go back there again or am I deemed to have enough brains to read instructions on PC? One of my confusions was that, in an Outlook.com account which was named (******@Cox.net) I was asked to give my password which I thought meant my Cox.net password but actually meant my Outlook.com password, forcing me to get a new password for Outlook.com just to get into my new, Windows 8 computer. Please help. Else it's off to AT&T and the long lines again...
