Here's the situation. A friend freelances for an organization, and she wants to control mails she receives outside of working hours. Normally Outlook displays a sort of popup when you're composing mail to someone whose 'Out of office' is active (as does Lync 2010). She wants a similar way to notify someone who is composing a mail to her, if that person is composing the mail outside of her office hours.
The second suboptimal solution is to have an autoresponse sent for incoming mail sent outside working hours, say after 6 PM. However,there don't seem to be rule criteria for rules based on the time an email was received.
Is there a way to do this, perhaps by some third party addon?
