Hi,

I've a problem. I need to retrieve all contacts stored in a public folder in the ms exchange 2003 server in VB.NET or C#.

Anyone can tell me a way to do it or some example ?

Thank you.

I just struggled for 2 days to solve this same problem for my company--except I'm using PHP. Your job should be a bit easier since all the official examples are in VBScript, VB, VB.NET, C#, or C++.

I would direct you to the Microsoft WebDAV Reference wth code examples. Click "Exchange Store WebDAV Protocol", then explore the Methods from there.
http://msdn.microsoft.com/library/de...ces_webdav.asp

In dealing with Contacts, you'll also find this reference helpful--it lists all the Exchange "person" properties and their schema type.

I have documented my PHP solution. It's brand new and works, but no doubt I'll be improving and expanding it as time goes by. Notice my last code example is "Search for contacts that match a certain criteria". This example is close to what you want to do. Although my code is PHP, the actual WebDAV XML query is the same as you need--and that's the trickiest part of WebDAV.

Console.Write(oItems.Count)

Dim i As Int16 = 0
For Each item In oItems
Try
Dim oCt As Outlook.ContactItem
oCt = item
Console.WriteLine(i.ToString + " - " + oCt.FullName)
i = i + 1

'Need to release Oct because it craps out at 247 records with the following error
