Outlook account not adding to live mail

I only created an outlook email account only on Monday and added to Live mail and it worked I was getting my emails and following outage yesterday it came up with deltasync error. I hoped once the servers were back on line it would just fix itself but it hasn't. I have remove the account and tried to re-add but now it asking to man configure. I had typed all the information in then click to download files and its rejecting my user name /password even though I am logging into my account with the same. I managed to get it linked to my ipad but I really want it on my live mail account.  I had a chat with a tech last night and tbh and was just directed to the guidance I was already using.  I've no clue why it is not working to sync.  I did make a slight change to my password via another computer but  thought I would need to just need to update on my home pc in live mail.    Can anyone help?
