I am in the process of changing my provider, so will lose my O2 addresses.  So that I can change providers more easily in the future I signed up for a couple of outlook.com & gmail addresses only to find I can't use them with Windows Mail (Vista).  Having used WM for several years I have my Contacts & folders set up to suit my way of working.  Have imported contacts list into Outlook but can't get on with it.  Evidently it is not possible to install Windows Live Mail as it is no longer supported for Vista.   Is there any other option that works like WM?
