SUMMARY

The Microsoft OLE DB Provider for Internet Publishing (MSDAIPP), also known as Internet Publishing Provider (IPP), can be used to access data in an Exchange Server Web Store. This article describes how to set up the provider for remote access.

MORE INFORMATION

MSDAIPP communicates to its data source through Web Distributed Authoring and Versioning (WebDAV). Because the Web Store understands WebDAV, MSDAIPP can be used to communicate with Exchange. MSDAIPP takes a Hypertext Transfer Protocol (HTTP) Uniform Resource Locator (URL) for its connection string. The format is as follows:
http://servername/path
For example, to access the Inbox of the Administrator's folder on the myserver.microsoft.com server, you could use the following URL:
http://myserver.microsoft.com/Exchange/Administrator/Inbox
To access a message in a public folder, you could use the following URL:
http://myserver.microsoft.com/Public/MyPublicFolder/MyMessage.eml
The following code demonstrates how to use MSDAIPP to connect to an object in an Exchange Web Store.
Function GetRecord(Server As String, Path As String) As ADODB.Record
    Dim cn As New ADODB.Connection
    Dim rec As New ADODB.Record
    Dim strURL As String

    On Error GoTo err
    
    'Create the URL to the folder.
    strURL = "http://" & Server & "/" & Path

    cn.Provider = "msdaipp.dso"
    cn.Open strURL
    
    'Open it.
    rec.Open strURL, cn, adModeReadWrite, _
      adCreateOverwrite Or adCreateNonCollection

    Set GetRecord = rec
    
err:
    If err.Number Then
        Debug.Print "Error: " & err.Number
        Debug.Print "Desc: " & err.Description
        Debug.Print "Source: " & err.Source
        err.Clear
    End If
End Function
				
IMPORTANT: MSDAIPP is not supported for use with Collaboration Data Objects for Exchange 2000 Server (CDOEX).

Also, MSDAIPP cannot run directly on the Exchange Server. Because MSDAIPP uses the WinInet application programming interface (API) to manage its HTTP connections, it is not supported in middle-tier or server-side applications. Applications that run directly on an Exchange 2000 server should use EXOLEDB instead.
