Our ASP.NET application uses ELMAH to send error notifications via email. When this happens, I get the email on my phone and am notified via tone that a new email has arrived. However, at night, I turn my phone's volume off so I don't get woken up by errors that result in the user playing around with the query string. Some errors, though, I want to know about and even wake me up at night. Is there some way that, for certain emails, I can have Outlook on my Windows 7 phone ignore my phone's volume setting and make a tone even if I have it set to only vibrate?
