Hi @Thomas Grasso

Thank you for posting your query on Microsoft Q&A.

I understand that your microsoft accounts have been compromised and used maliciously.You are trying to shut down but before that you need to leave the organization.

I Recommend Changing Your Password Immediately and Use a strong, unique password that you haven't used before and go for strong MFA settings.

To leave the organization. Follow below document:
