The company later admitted that the problem had been far greater: between January 1 and March 28, about 6 percent of the intercepted accounts would also have had compromised message content. No corporate accounts would have been affected, but the company has not yet disclosed the number of personal profiles involved.

The criminals exploited a security hole in Microsoft's support service to retrieve email data from users. Most of the information was restricted to addresses, email subjects and personal folder names created on the web version of the services. However, attackers were also able to access the body of messages exchanged by some users.
Microsoft only admitted the seriousness of the problem after the US technology portal Motherboard had access to an official message alerting the most affected group of users, containing more detailed safety instructions. According to the publication, a source linked to Microsoft also reported that the stolen data would have been under the control of criminals for longer, at least six months.
Full email access, according to Motherboard, would have been used by hackers to reset iCloud accounts and unlock stolen iPhones. Microsoft did not detail whether the hacked accounts were used for this purpose.
According to Microsoft, breaking into Outlook accounts did not allow access to passwords or other login credentials. Still, the company recommends that users reset their account access data as a precaution. See how to do this in the following tutorial.
