Based on your description, after discovering the hack, you successfully changed your password and can now receive incoming emails normally. However, there is still a block on your outgoing emails, and even though you are the global admin, you are currently unable to lift this restriction.
To help me guide you to the exact setting in the admin portal to unblock your account, could you please provide a bit more detail?
- What specific Non-Delivery Report (NDR) or bounce-back error message do you receive when trying to send an email?
- If possible, please share the exact error code of that notification in private message.
Once I have this specific error information, I will be able to provide you with the technical steps to unblock your outbound email access in the Microsoft 365 Admin Center. Looking forward to your reply so we can resolve this together!
