How to collect email addresses from an Outlook email folder?

Is there a way to gather all email addresses (either from, to, or cc) in a particular email folder in Outlook and store them in a delimited file? Alternatively, is there a way to add all email addresses from all emails in a particular folder to Outlook Contacts or to the Outlook Address Book?

My problem is this: my phone number is changing and I'd like to send an email to everyone who has either sent me an email or to whom I've sent an email announcing the change.

Any other way to solve the problem?

I'm running XP Pro and Outlook 2003 (11.8217.8221) SP3.

Thanks.

 

That program (http://www.snapfiles.com/get/NK2View.html ) looks extremely helpful - thanks.

It should help gather all email addresses that I sent to...is there another similar tool for all addresses that I received an email from? It also likely won't pick up email addresses that I replied to but did not type in via keyboard/autocomplete.
