Pulling data from outlook

Hello,

Here is my situation:

Firstly I have imported outlook contacts into access (roughly 60,000), access gave the name 'all users'.

Next, I have a form (frmCSOrequest) with 4 text boxes COSid, CSOname, CSOLocation, CSOemail that are all bound to a table (tblMain).

In my mind this is what I would like to do:

Have a button that once clicked will bring up an input box, the user will then enter the CSOid which will lookup the linked outlook table and populate the 4 text boxes with the relevant data (Id, name, location, email).

I was hoping someone could point me in the right direction in what to search for, as I have no idea (what I've searched for so far has given me zippo)

Or am I even on the right track in my thinking of what I want, if there is a better method please let me know.

Many thanks!
Jeremy.
