Last month I complained about the speed of Outlook.com after I was changed from hotmail.com - after various back and forths and hundreds of messages from Microsoft and other users regarding this issue, it seemed to have been resolved.
But, now it's back!
PLEASE, Microsoft!! - Undo whatever you have just done (I suspect we were routed to the US servers but have now gone back to the European ones) !!

Even this small message has taken several minutes because it's lagging so badly!

Thanks, bartoPL
