iPhone keeps asking for Outlook email password

I had an account set in outlook to my apple email address. Yesterday a pop up kept appearing to input my password. I entered my apple password and still kept popping up. In my frustration I deleted the apple email account from outlook and figured I would just add it again as a new account. I have followed the instructions found on the internet for adding an apple email address to outlook and the pop up for a password still continues to pop up. How do I get this resolved? I entered the account with my apple email address, apple password, incoming email as imap.mail.me.com, outgoing as smtp.mail.me.com, input the user id as my apple ID email address, input my apple password, went to advanced and changed incoming to 993 SSL and outgoing to 587 SSL. Still will not add the account. HELP
