Hi, try deleting ALL references to Hotmail. To do that, open the 3-bar menu > Library > History, then click the Show All History link at the bottom of the list to open the History-library window. Search for Hotmail by typing it into the Search History field in the top right corner. Now in the search results, right click on Hotmail, and select Forget About This Site. (Browsing and download history, cookies, cache, active logins, passwords, saved form data, exceptions for cookies, images and pop-ups for that site will be removed). Give it a minute to complete the deletion, then try the site (not from an old bookmark) again.
