I would like confirmation that the at-rest encryption is also provided for the personal OneDrive storage that comes with Office 365 Solo in Japan. The only documentation I can find is translations of English Microsoft webpages. These Japanese pages all carry disclaimers that services vary by region. Even the OneDrive email-only help center in Japan didn't now the answer! I find it hard to believe that such basic information on such a fundamental security feature is not readily available in every country.
