OK, WebDAV does not have the ability itself to get a list of mailboxes.  However you can use other APIs and even use an OWA call to get a list of mailboxes.


Reading the GAL:


WebDAV itself cannot do this.  You could use the OWA GALFIND command, which has some limited ability.  You could also use ADSI, CDO 1.21 or Extended MAPI as long as you’re running in-network.  There is no Exchange Web Service (EWS) call for doing this (at least not in Exchange 2007 SP1)).




GALFIND is an OWA call which is supported to use.  It is not a WebDAV call.  Basically, you do a GET against a URL and pass it search parameters.


Format of the OWA call:


sServerURL = "http://"+ sServerURL + "/public/?Cmd=galfind


Information on the unsupported call is covered in the following article:

Customizing Microsoft Outlook Web Access



Basic call - use the following URI and choose "GET - OWA Call" - you will not need a body, all info past to OWA are in the uri:


http://<Exchange server>/exchange/?cmd=galfind


Here are the possible search Parameters:


      DN        Display Name                ex: Robert Jones

      FN        First Name                     ex: Robert

      LN         Last Name                    ex: Jones

      TL         Title                              ex: Big Manager

      AN        Alias                             ex: bobj

      CP        Company                      ex: microsoft   

      DP        Department                    ex: Exchange

      OF        Office                            ex: Bld 15/2124

      CY        City                               ex: Redmond


Note: There is no ability to search against other fields such as phone number, etc.

More on using Extended MAPI to read the Mailbox Table:


The Mailbox Table in Exchange holds a list of Mailboxes and related mailbox information.  Reading this table can only be done with Extended MAPI or WMI can be used on an Exchange 2003 server.   


Extended MAPI can be used with Exchange 5.5 and later.

Here is a sample of using GALFIND:


'  GALFIND Sample

' GALFIND will return results which can be consumed by your application as xml.

' You can test the URL by putting it into IE and seeing the results.

'  TODO: Have Basic Authentication turned ON on the virtual directory for the item and no anonymous.

'  Note: there is no Translate header set for a GET against an OWA URL – That’s because we are not using WebDAV, we are using the results from an OWA page.
