Managing personal Outlook.com account settings, security, and privacy
If the sign-in email was changed and signing in with the old address now says the account does not exist, the supported recovery path is the Microsoft account recovery process for a hacked account.
- First, scan the PC for malware before changing any passwords:
- Open Virus and threat protection
- Select Scan options > Full scan > Scan now
- Use the Microsoft account sign-in helper and hacked-account recovery flow.
- If sign-in still fails, use Forgot my password on the sign-in page and select I think someone else is using my Microsoft account.
- Complete the Microsoft account recovery form with as much detail as possible:
- Provide a working email address that can receive the recovery result
- Include as much account history as possible
- For Outlook.com/Hotmail.com accounts, exact email subject lines and contact details can help
- Wrong answers do not count against the request, so incomplete details are still worth submitting
- After submitting the recovery form:
- A result is sent to the working email address within 24 hours
- If the account is verified, instructions to sign back in are sent there
- If it is not verified, the form can be retried up to two times per day
Important:
- Support agents are not allowed to reset the password or change account details directly.
- If the attacker changed the associated email or security information, recovery may no longer be possible through self-service. The available supported path remains the hacked-account and account-recovery process.
