The company first released a statement on Friday to Outlook users, notifying people that a hacker had had access to emails for months after stealing login credentials for a Microsoft customer support agent.

The breach, first reported by TechCrunch, allowed potential hackers to access people's emails and read folder names, subject lines and names of other email addresses. Microsoft said it's since disabled stolen access to the hacked customer support agent's account.
