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.
