Email addresses in Exchange

Is there anyway of extracting all email addresses out of an MS exchange, these would include all contacts for all users, all users emails addresses, even all email addresses that they have ever sent to ???

Please Help ??

Wow, that's a tall order.  Exchange doesn't keep such records.  Tracking logs are only saved for 7 days by default.

There actually is a way to get many of the addresses that have been sent to if auto-complete was enabled for users in Outlook.  Those would be on each workstation in a binary file named something like:  C:\Documents and Settings\%USERNAME%\Application Data\Microsoft\Outlook\USERNAME.NK2.  But they would still be difficult to extract.

There are third party tools that will grab the information as it flows, but forensic data will be difficult to come by (unless the messages are still stored in a user's mailbox, in which case some of the third party tools can extract the info).
