  • Artykuł

We can get Internet Headers/Message Headers via WebDAV using PR_TRANSPORT_MESSAGE_HEADERS MAPI property.

PidTagTransportMessageHeaders Canonical Property

PR_TRANSPORT_MESSAGE_HEADERS

Here is VBScript sample with WebDAV PROPFIND request.

NOTE: Following programming examples is for illustration only, without warranty either expressed or implied,
including, but not limited to, the implied warranties of merchantability and/or fitness for a particular purpose.
This sample code assumes that you are familiar with the programming language being demonstrated and the tools used
to create and debug procedures.

 

 Dim objX, strR, strRes

 Set objX = CreateObject("Microsoft.XMLHTTP")

 'Change Item URL, Domain, User, Password

 objX.Open "PROPFIND", "https://server/exchange/user/Inbox/Item123.EML", FALSE, "Domain\User", "Password"

 strR = "<?xml version='1.0'?>"

 strR = strR & "<d:propfind xmlns:d='DAV:' xmlns:m='urn:schemas:mailheader:' "

 strR = strR & "xmlns:e='https://schemas.microsoft.com/exchange/' xmlns:p='https://schemas.microsoft.com/mapi/proptag/'> "

 strR = strR & "<d:prop><d:displayname/><p:0x007D001f/></d:prop></d:propfind>"

  

 objX.SetRequestHeader "Content-type:", "text/xml"

 objX.SetRequestHeader "Depth", "1"

 objx.SetRequestHeader "translate", "f"

 objX.send(strR)

  

 strRes = objX.responseText

 Msgbox strRes

 

And following is sample WebDAV SELECT request.

 <?xml version="1.0"?>

 <D:searchrequest xmlns:D = "DAV:">

 <D:sql>SELECT "urn:schemas:mailheader:to", https://schemas.microsoft.com/mapi/proptag/0x007D001F, "urn:schemas:httpmail:subject" FROM "/exchange/user/Inbox/" 

 WHERE "DAV:ishidden" = false AND "DAV:isfolder" = false</D:sql>

 </D:searchrequest>
