the shared mailbox deleted also from online exchange 365

and delete user from on prem AD list

You cannot delete the user object. Mailboxes, shared ones included, all have an underlying user object. If you delete the user, or exclude it from the scope of sync, the mailbox will be gone as well.

So there is no option to save mailbox as Shared and delete the user?

No, there needs to be a user object for every shared mailbox.
