Export mailbox contacts to delimited file

[johnaregan]

Hi
Does anyone know how I can go through each Contacts folder in every Mailbox on the Exchange Server and export the contacts to one delimited file (I have administrator access).

All of our mailboxes are stored on the Exchange server (ie. we do not use .pst files).

I have read about command line tools like admin.exe, csvde but cannot get enough info to be able to go ahead with this. I have also read about Exmerge, but this tool puts the info into individual pst files.

Any help would be much appreciated.
