Outlook email users alerted to suspicious activity from Microsoft-owned IP address

UPDATED Strange things are afoot in the world of Microsoft email with multiple users reporting unusual sign-in notifications for their Outlook accounts.

While an unusual sign-in activity email should always be treated with suspicion, the twist here is that the IP address at the root of the issue appears to originate within Microsoft itself.

The messages, according to users, also appear in the unusual activity section of the company's email website, ruling out a phishing attack. Some confirm that an automatic sync has occurred.

Microsoft's support forums are full of customers confused and a little concerned about the notifications, which look for all the world like either Microsoft or a miscreant with access to one of the company's endpoints is seeking to access their mailbox. Users have wisely changed passwords, but still occasionally see a successful sync among the failed login attempts.
