SYMPTOMS

Consider the following scenario:
  • You have a computer that is running Windows Server 2008 R2 or Windows 7.
  • You try to access some documents that are stored on a Microsoft SharePoint site by using the Web-based Distributed Authoring and Versioning (WebDAV) protocol. The documents are Information Rights Management (IRM)-protected.
In this scenario, you may be unable to open the documents.

The following is a sample scenario:
  • You try to open an IRM-protected Microsoft Office Excel workbook that is stored on a SharePoint site.
  • You are prompted that the document is currently restricted and that Microsoft Office needs to check the licensing and verify your credentials.
  • You click OK, then you receive the following in a pop-up dialog box:
    ERROR: Excel found unreadable content in <file name>. Do you want to recover the contents of this workbook? If you trust the source of the workbook, click Yes.
  • You click Yes, and then Excel suddenly stops and restarts. However, the document is never opened.

CAUSE

This issue occurs because the WebDAV client does not open the shared documents by using the correct shared access mode.
