Inactive User Auto Response

Inactive User Auto Response

We use Zoho One, and we have a couple employees that are no longer with us, but people are still attempting to email them.  I'd like an autoresponder to let them no the person is no longer here, and how they can reach us going forward.

I saw a similar post that says to use a vacation reply, but this does not work when the user is made inactive.  Any attempts to email the user results in a 'address cannot be found' server error message, and the email is not delivered even if forwarding is enabled.  Past users must be marked as 'inactive' so they don't consume our Zoho One licenses.

Can someone help us understand how to redirect customers who attempt to contact past employees marked inactive?  I would assume this affects every Zoho client who has had an employee, right?
