Is there anyone have experience in Exporting Ms Exchange (with AD2000) user information to a TEXT File and import them into IMail (using adduser.exe) ?

I need help urgently.

Please Advice.

I don't really see the need for an intermediate text file.

You can download ldap2aliases (see my sig) for pointers on how to grab information from AD.  It's designed for IMail MXs in front of Exchange mailbox servers, but parts of the code can be adapted to get what you want.

There's also another way to turn AD users into IMail users, if your userbase isn't too large: make your mailserver an AD DC and set up a domain that uses IMail's NT integration option.  Then, one-by-one, select each user in the IMail Administrator, which will bring the user's username and full name into the Registry.  Change the domain back to an IMail native (Registry) domain and the users will be IMail users.
