Email sent to 2 addresses with shared same organization domain and one bounced back. Was it successfully delivered to the other address?

It is my first time asking questions, so my apologies if there is any mistakes. I sent an email to 2 addresses (2 different departments in same organization with shared, one bounced back from due to ‘address not found’. I later found out it was a generated email address. Could someone please tell me if my email was successfully delivered to the other ‘good’ address (the other department)? Thank you very much for your great help in advance.
