Where does mail go when you use Delayed Delivery?

Here I was thinking this was a no brainer when I got asked this question, however when you think about it a bit you start to find large areas of grey.  I originally had two lines of thought when it came to the answer and as it turns out both were right but only for certain versions of Outlook.

As I suspected, the mail is actually submitted to the IS and sits in the mail queue (see below) in the newer version of Outlook 2003.

Outlook 2003 - "Do not deliver before"
From http://support.microsoft.com/kb/823489/en-us Here is a snip from the article....
__________________________________________________________________________________________________
Queue: Messages queued for deferred delivery
First Available: Exchange Server 2003
Description: This queue contains messages that are queued for later delivery. It includes messages that were sent by older versions of Microsoft Outlook when this option is set. Newer versions of Outlook queue these types of messages in the information store. These messages remain in this queue until their scheduled delivery time.

More Interesting stuff:
