Currently, if a workflow attempts to route to a leaver (deactivated user), the workflow fails. Even sysadmins are not able to reassign it to another user. It is a pain to sort out these issues - as an example we have to take a PO to draft, change the orderer on a PO and take it back through approval, so that the invoice workflow which routes to the orderer does not fail.

As a team manager, our user would the ability to set up a delegate for a leaver, and this delegate continue to receive workflow items that would have

This could be achieved by updating workflow logic to, when it encounters a deactivated user, consider whether there is a delegate in place and route to the delegate before erroring.
