Microsoft says it has resolved Outlook email filter outage that resulted in a deluge of spam
Users of Microsoft's Outlook.com have been flooded with spam and phishing emails over a period of 12 hours. It seems that the message filters for the email service suffered an outage, resulting inboxes being overwhelmed with junk mail.
While Microsoft says that the issue has now been addressed, the company has provided very little in the way of explanation for what happened.

The service status page for Outlook.com now indicates that "everything is up and running", but the status history reveals just a bit about what has been going on.
Microsoft only provided two status updates during the spam filter outage, with the first saying:

The near-radio silence from Microsoft about the problem -- which affected a large but unknown number of people -- has irritated many. There were numerous complaints on Twitter when the issue reared is head, and the company only responded to tweets when the issue was resolved:
While the issue may be fixed, anyone who does not check their email frequently may still be astonished to find a mountain of spam waiting for them when they do access their inboxes.
