Symptoms

You use the WebDAV DELETE method to delete an attachment in an e-mail message in Microsoft Exchange Server 2003. This e-mail message was sent by a non-MAPI client. In this scenario, the WebDAV DELETE method may fail with a 409 error message. Additionally, the name of the attachment now has a URL that contains the following text:
1_multipart_xF8FF_2

Workaround

To work around this problem, use a PROPPATCH method in a field which is rarely used in the e-mail message. The PROPPATCH method will force Microsoft Exchange Server to convert the e-mail message to the MAPI format. If the e-mail message is converted to the MAPI format, the WebDAV DELETE method works as expected.

The following is an example of the code that you use to convert the e-mail message to the MAPI format:
<?xml version='1.0'?>" "d:propertyupdate xmlns:d='DAV:'
     xmlns:m='urn:schemas:mailheader:'>
     <d:set><d:prop>
     <m:comment>anytext</m:comment>
     </d:prop></d:set></d:propertyupdate>
Note When the PROPATCH method is finished, the e-mail message is put in the .Edb file. After the conversion is complete, the attachment will have a new URL. This new URL can be used with the WebDAV DELETE method.
