Alert Condition for Linked Mailbox

Over the years, we have had to reauthenticate/link our linked mailbox a few times, which we use for alerts. It's not a big deal, but we often don't realize until something happens and we do not receive an alert. It would be helpful if there were a notification condition for troubled linked mailboxes that we could then alert on with the webhook action or ACS. Applying this same logic to any of the delegated permission auths at the client level under integrations may be beneficial, too. Essentially an alert condition for any troubled "linked" account.
