Are you NOT getting emails from your Hotmail? If yes, you might want to check the “deleted folder” because according to source, many people encountered this scenario over the New Year.
Seems that many people are already complaining. I don’t use my Hotmail account. I have only 2 emails in my Inbox and none in my deleted folder. Nevertheless, if you are Hotmail users, do check the deleted folder.
No official words from Microsoft yet but seems like the Microsoft technical people are busy answering questions over at their forum.
