I have just updated (Tue) my Nokia Lumia 520 with the Cyan 8.1 install, and now my hotmail acc. seems to be out of action? when open acc am asked to continue using hotmail on yours phone you need to give windows phone permission to access your acc. am then given options to either connect or cancel, but when try to connect the screen goes blank and nothing happens whatsoever??? when I return to the acc it only shows emails, messages etc up till Tue when the upgrade was implemented. This acc was/is my live acc. I tried sync Ing worth outlook acc but was still unable to gain access to and receive data to my hotmail acc. I have other email accounts e.g outlook, Gmail, Nokia mail and of course my m Microsoft acc. I live in Scotland and worth "3"if this helps? Am a newbie to smartphones this being my 1st one so be gentle
