To get a collection of room lists

  1. Instantiate the EmailAddressCollection object by calling the GetRoomLists method of an ExchangeService object named service.

    // Return all the room lists in the organization.
    EmailAddressCollection myRoomLists = service.GetRoomLists();
    
    
  2. Display the room lists.

    // Display the room lists.
    foreach (EmailAddress address in myRoomLists)
    {
         Console.WriteLine("Email Address: {0} Mailbox Type: {1}", address.Address, address.MailboxType);
    }
    

The following example shows how to display a collection of all room lists that are returned from a server.

private static void GetRoomLists(ExchangeService service)
{
    // Return all the room lists in the organization.
    EmailAddressCollection myRoomLists = service.GetRoomLists();

    // Display the room lists.
    foreach (EmailAddress address in myRoomLists)
    {
         Console.WriteLine("Email Address: {0} Mailbox Type: {1}", address.Address, address.MailboxType);
    }
}

The following example shows the XML that is sent by using the GetRoomLists method.

  <?xml version="1.0" encoding="utf-8"?>
  <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <soap:Header>
      <t:RequestServerVersion Version="Exchange2010_SP1" />
    </soap:Header>
    <soap:Body>
      <m:GetRoomLists />
    </soap:Body>
  </soap:Envelope>

The following example shows the XML that is returned by the GetRoomLists method.

For information about compiling this code, see Getting started with the EWS Managed API 2.0.

  • Write appropriate error handling code for common search errors.

  • Review the client request XML that is sent to the Exchange server.

  • Review the server response XML that is sent from the Exchange server.

  • Set the service binding as shown in Setting the Exchange service URL by using the EWS Managed API 2.0. Do not hard code URLs because if mailboxes move, they might be serviced by a different Client Access server. If the client cannot connect to the service, retry setting the binding by using the AutodiscoverUrl(String) method.

  • Set the target Exchange Web Services schema version by setting the requestedServerVersion parameter of the ExchangeService constructor. For more information, see Versioning EWS requests by using the EWS Managed API 2.0.

  • Use HTTP with SSL for all communication between client and server.

  • Always validate the server certificate that is used for establishing the SSL connections. For more information, see Validating X509 certificates by using the EWS Managed API 2.0.

  • Do not include user names and passwords in trace files.

  • Verify that Autodiscover lookups that use HTTP GET to find an endpoint always prompt for user confirmation; otherwise, they should be blocked.
