This is what I would like to accomplish:

When a new email with an already known email address arrives in the Inbox folder I would like to be able to raise an event that calls my dll to process this incoming email.

Is there a way to monitor for this incoming email without the use of continually scanning the Inbox every minute or so?

Is there an Outlook event that fires when an email arrives to the Inbox?

Thanks in advance for all and any help.
