I only use live email. And have done nothing for this to happen apart from recently updating to the new "Explorer 9"

[Moved]

When I send an Email, nothing's worse than not knowing if it's been opened and ignored or just trashed.  How can I tell if it's been opened? 

Logged into messenger today and all but 1 contact has vanished. Nothing new or different on my end to the usual day. No settings changed from me.

does anyone know if i can retreive my contacts?

When I try to delete messages in my inbox I get "Sorry, something went wrong. Please try again, or refresh the page.  If you keep seeing this message, go to Service status to check if there's a problem with Hotmail." The messages do not delete and message says Live Mail is "normal".

I have tried rebooting, and other disk cleaning methods. Nothing seems to work.
