When you try to access a Microsoft Exchange 2000 Server mailbox or a Microsoft Exchange Server 2003 mailbox by using a program that uses Web Distributed Authoring and Versioning (WebDAV), Microsoft Internet Explorer may return a 401 status code. Additionally, you may not be able to access the mailbox, and the following event may be logged in the application log:
This behavior may occur when either of the following conditions is true:
To work around this behavior, log on to the mailbox by using one of the following clients before you run the WebDAV program:
When a mailbox object is created in the Exchange information store, the mailbox object is not available by WebDAV until the mailbox is accessed through a client logon. If the mailbox receives an e-mail message, the mailbox object becomes available, but not in a way that permits the WebDAV program access. Therefore, the problem still occurs.
