BOSTON — State-backed Russian hackers broke into Microsoft's corporate email system and accessed the accounts of members of the company's leadership team, as well as those of employees on its cybersecurity and legal teams, the company said Friday.

In a blog post, Microsoft said the intrusion began in late November and was discovered on Jan. 12. It said the same highly skilled Russian hacking team behind the SolarWinds breach was responsible.
