Managing personal Outlook.com account settings, security, and privacy
For security reasons, Microsoft employees do not have access to your account. Only the automated tools can change your account. You can use this forum or chat for help on how to use the tools, but again no employee can change your account. If you explain exactly what hacked means, this forum can give more suggestions.
If you can no longer login in to your account, you will need to use the account recovery form. You will need to provide proof the automated tools can use to verify your ownership. You can try twice a day, and recovery once your proof is accepted takes about 30 days.
