Harvest Email list from our 2003 server for change of address list

We have just moved offices and changed numbers etc.  We want to Email everyone of our clients to let them know.  However our database (Goldmine) has not got a full list of email addresses.  Is their a way of collecting the information from the Exchange 2003 server     ie   a list of email addresses that we have sent to in the past. ?

Any Ideas welcome

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Don't you have the email addresses in Exchange / Outlook? Regarding Goldmine, why not ask them?
Check you sent items folder.
Hello micinamike,

You can use a third party program like Outlook Extractor Pro

Hope this helps!
