Webdav htmldescription tag missing from response

We have some code that's reading HTML emails from an exchange mailbox using
Webdav and has been quite happy for sometime. A snippet of code from it is as
follows:

strMailboxURI = "http://10.88.12.240/exchange/andrewp/inbox"
oXMLHTTP = New MSXML2.ServerXMLHTTP40
oXMLHTTP.open("PROPFIND", strMailboxURI, False, strAlias, strPassword)
oXMLHTTP.setRequestHeader("Content-type", "xml")
oXMLHTTP.setRequestHeader("Depth", "1")
oXMLHTTP.send()
Dim XMLDocument As System.Xml.XmlDataDocument
XMLDocument = New System.Xml.XmlDataDocument
XMLDocument.LoadXml(oXMLHTTP.responseText)
DisplayNameNodes1 = XMLDocument.GetElementsByTagName("e:htmldescription")
If DisplayNameNodes1.Count > 0 Then
DisplayChildNodes = DisplayNameNodes1.Item(0).FirstChild
strHTMLBody = DisplayChildNodes.InnerText()
end if

So if there were any emails within the inbox we used to get the html content
stored with strHTMLBody for further processing.

Something must have changed, and not the coding, but the process stopped
working, now when we run the same code we don't get any htmldescription tags
at all within the XML document returned from Exchange.

Would anyone have an idea why this might happen? Or suggestions for using
webdav another way to retrieve this information.

A snippet of what is returned is this:

<?xml version="1.0"?>
<a:multistatus xmlns:b="urn:uuid:c2f41010-65b3-11d1-a29f-00aa00c14882/"

Hello,

the reason why no html description is returned in this case, is that you are
performing the webdav query on a folder (iscollection=1).

If you want to look for all items in a folder, you should stick to a SEARCH
command.

Best regards,

Thanks Henning,

So I've converted the code to use the following search string but still I
don't get either the htmldescription or text descriptions back from exchange
in the response.

The search string I'm using is:
<?xml version="1.0"?>
<D:searchrequest xmlns:D = "DAV:">
<D:sql>
SELECT "DAV:contentclass", "DAV:displayname", "DAV:htmldescription",
"DAV:textdescription"
FROM "http://10.88.12.240/exchange/andrewp/Inbox/"
WHERE "DAV:ishidden" = false
AND "DAV:isfolder" = false
</D:sql>
</D:searchrequest>

The response begins:
<?xml version="1.0"?>
<a:multistatus xmlns:b="urn:uuid:c2f41010-65b3-11d1-a29f-00aa00c14882/"
xmlns:c="xml:" xmlns:a="DAV:">
<a:response
<a:href>http://10.88.12.240/exchange/andrewp/Inbox/Trade%20Me%20Jobs%20--%20New%20application.%20Job:%20MILACKIT001%20Systems%20Support%20Administrator-3.EML</a:href>
<a:propstat><a:status>HTTP/1.1 200
OK</a:status><a:prop><a:contentclass>urn:content-classes:message</a:contentclass><a:displayname>Trade

<a:propstat><a:status>HTTP/1.1 404 Resource Not
Found</a:status><a:prop><a:htmldescription/><a:textdescription/></a:prop></a:propstat>
</a:response>

Could you let me know what I'm doing wrong here?

Thanks........

Hi Andrew,

you are quering the wrong properties.

Instead of DAV:htmldescriptions, you must query
urn:schemas:httpmail:htmldescription
