I am very sorry, but I have to post yet another question:

in my desktop Windows Live Mail I have two accounts. I use one account for synchronising my mail with the online version of Windows Live Mail (I sign in with Windows Live ID and everything works fine). However this doesn't work for Contacts and Calendar - whatever I create locally doesn't show up when I sign in with Windows ID (I create something locally, it doesn't show up online; I create something online, it doesn't show up locally).

So this is really frustrating. I very much hope someone can help.

Thank you.
