Outlook has stopped recognising my password, i am unable to access my account.

Hi All

Can't access my outlook account, password not accepted although it is the correct password. Have had a link sent to me from Microsoft but when I click on the link what comes up is 'There's a temporary problem', this message has been showing for a number of weeks now and doesn't show any signs of changing. Is there any way I can access my account given these circumstances? All help gratefully received, many thanks.
