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.
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:
For example, to access the Inbox of the Administrator's folder on the myserver.microsoft.com server, you could use the following URL:
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 IfEnd 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.
