A statement isssued by Microsoft revealed that the company is looking into reports that some users of its Hotmail service were accidentally shown other users' inboxes when attempting to access their mail through their mobile phone. The Windows Live sign-in service was down for an hour yesterday; whether the two events are related is as-yet unknown. The sign-in downtime was purportedly due to a server failure, and left many unable to log in to any Microsoft service dependent on Windows Live IDs, including both Hotmail and Windows Live Messenger.
In its statement, the software giant said "Microsoft takes customers' privacy seriously, and immediately upon learning of these reports, we started an investigation. We will take appropriate action once we have completed the investigation."
