Collect All Contacts of All Mail Users

Hello
We want to extract all the contacts that has ever send/receive emails to/from all the users in the company.

I have looked into the following solutions but each has its own problems. Are there workarounds of these problems? Are there other solutions out there?

- NK2 file: has 1000 contacts limit; and I know some users definitely have way more than 1000 contacts

- Address Book: Some users do not have a habit of saving contacts, therefore their address book is 0.

We use Outlook Exchange mail server.

If your Exchange data store includes all messages ever sent/received then you can go message by message and enumerate the recipients...

Hi, RNGAdmin.

The NK2 file only contains addresses that have been typed into the To/CC/BCC line of an Outlook message.  It does not contain the addresses of received messages nor does it contains addresses selected from an address book.  matthewspatrick's suggestion is the only solution.  We can script the process, reading all messages in a mailbox and collecting the addresses in a file.  The problem is how to deploy that.  The script would have to run at each client.  Outlook does not have an automated means of deploying code.

We wanted to avoid labor-intensive solutions so eventually we chose to use a software that reads NK2 files and extract all users' NK2 contacts...but this is not the perfect solution, as some contacts fail to be captured by NK2...such as the 2000 max contact in 2007 and 1000 in 2003.
We look forward to any future discussions regarding this issue

RNGAdmin,

With respect, I think your award of a 'C' on this is patently unfair.  It is hardly my fault that the only way to get what you want ("We want to extract all the contacts that has ever send/receive emails to/from all the users in the company.") is what I suggested and what BlueDevilFan (who is himself a Microsoft MVP for Outlook) has confirmed.

As BDF notes, my suggestion can be automated with code; my notion was to go up against the Exchange data store directly and thus cut Outlook out of the loop (and also potentially allow you to "resurrect" contacts from messages users may have deleted but which still exist in Exchange), although BDF's suggestion to run the code for each Outlook client is certainly viable.

Indeed, the alternative you described is wholly inadequate, by your own admission, to answering your original question.

Dear matthewspatrick, you are right. The manual approach is the only option if we want to harvest all emails. Sorry for inadequate grade... It was not objective at all.
