The company stated in an official report that “This misconfiguration resulted in the potential for unauthenticated access to some business transaction data corresponding to interactions between Microsoft and prospective customers, such as the planning or potential implementation and provisioning of Microsoft services.” Also, no need to worry about the affected customers because they were notified on the same day of identification. According to Microsoft, the exposed information contains names, email addresses, email content, company name, phone numbers of customers, and files related to business between Microsoft and customers. And the company also noted that their last examination found no clue of compromisation regarding customer accounts or systems.
