Microsoft has started notifying some Outlook.com users that a hacker was able to access accounts for months earlier this year. The software giant discovered that a support agent’s credentials were compromised for its web mail service, allowing unauthorized access to some accounts between January 1st and March 28th, 2019. Microsoft says the hackers could have viewed account email addresses, folder names, and subject lines of emails, but not the content of emails or attachments.
