Yes that is correct. Enabling or disabling the user account on the shared the mailbox doesn't change anything about the mailbox. By default a shared mailbox is created with a disabled account so that account can't be used to login to any resources in the domain, but if you enable that account nothing changes with the mailbox but that account can now be permissioned to access network resources. The behavior you noticed is correct.

The definition of a Shared mailbox is an disabled account because it's not meant to be &quot;active&quot; or able to login with any identity, so it doesn't have an password either.

Shared Mailbox must be with a disabled AD account?
