- You have an email message that has an attachment in a Microsoft Exchange Server 2007 environment.
- The attachment itself is a signed email message that also contains an attachment.
- You try to use the X-MS-ENUMATTS method of Web Distributed Authoring and Versioning (WebDAV) to enumerate the attachment in the signed email message.
For example, the returned URL is expected to use the following syntax:
<path of server>/<path of outer message>/<path of inner message>/<path of attachment>
However, the returned URL uses the following syntax:
<path of server>/<path of inner message>/<path of attachment>
Because of this behavior, applications cannot enumerate an attachment correctly. Therefore, it effects applications that use WebDAV, such as Microsoft Dynamics, when they communicate with Exchange Server 2007 servers.
