c# - EWS - Get a user's peers (same manager) -

i'm trying exchange query user's peers, shown in global address list. first thought run query returns users same manager.

finditemtype request = new finditemtype(); distinguishedfolderidtype[] fid = { new distinguishedfolderidtype { id = distinguishedfolderidnametype.contacts } };  request.parentfolderids = fid; request.traversal = itemquerytraversaltype.shallow;  itemresponseshapetype props = new itemresponseshapetype(); props.baseshape = defaultshapenamestype.allproperties;  request.itemshape = props;  // insert restriction "someone@somewhere.com" = contactsmanager  finditemresponsetype response = _binding.finditem(request); 

unfortunately queries contacts list, not gal. how can correctly?

i cannot query ad (app intended run off of internal network) , don't use ews managed api various other reasons.

any appreciated.

here's example of how access gal using ews exchange 2007 , above; taken here see link valid pointers. code searches gal particular contact.

static void main(string[] args) {     exchangeservicebinding esb = new exchangeservicebinding();     esb.url = @"https://myserver/ews/exchange.asmx";     esb.credentials = new networkcredential(                           "username",                           @"password",                           @"domain");      // create resolvenamestype , set     // unresolved entry.     resolvenamestype rntype = new resolvenamestype();     rntype.returnfullcontactdata = true;     rntype.unresolvedentry = "test";      // resolve names.     resolvenamesresponsetype resolvenamesresponse = esb.resolvenames(rntype);     arrayofresponsemessagestype responses = resolvenamesresponse.responsemessages;      // check result.     if (responses.items.length > 0 && responses.items[0].responseclass != responseclasstype.error)     {         resolvenamesresponsemessagetype responsemessage = responses.items[0] resolvenamesresponsemessagetype;          // display resolution information.         resolutiontype[] resolutions =         responsemessage.resolutionset.resolution;          foreach (resolutiontype resolution in resolutions)         {             console.writeline("name: " + resolution.contact.displayname);             console.writeline("emailaddress: " + resolution.mailbox.emailaddress);              if (resolution.contact.phonenumbers != null)             {                 foreach (phonenumberdictionaryentrytype phone in resolution.contact.phonenumbers)                 {                     console.writeline(phone.key.tostring() + " : " + phone.value);                 }             }              console.writeline("office location:" + resolution.contact.officelocation);             console.writeline("\n");         }     } }
