Symptoms

When you work with the Exchange OLE DB provider (ExOLEDB), if you try to pass user name and password parameters to open an ActiveX Data Objects (ADO) Connection or Record object, you may receive the following error:
Run-time error '-2147217843 (80040e0d)': Authentication failed"

Cause

The Exchange OLE DB provider does not support authentication. The calls made when you use this provider run under the security context of the current application.

Workaround

You may want to use Web Distributed Authoring and Versioning (WebDAV) or Microsoft OLE DB Provider for Internet Publishing (MSDAIPP), which has the ability to authenticate by user name and password.
