Sample: Share a queue (early bound)

Applies To: Microsoft Dynamics CRM 2013, Microsoft Dynamics CRM Online

This sample code is for Microsoft Dynamics CRM 2013 and Microsoft Dynamics CRM Online. Download the Microsoft Dynamics CRM SDK package. It can be found in the following location in the download package:

SampleCode\CS\BusinessDataModel\BusinessManagement\ShareQueue.cs

SampleCode\VB\BusinessDataModel\BusinessManagement\ShareQueue.vb

noteNote
This sample for the Queue entity was not updated for changes introduced with Microsoft Dynamics CRM 2013 Service Pack 1 and Microsoft Dynamics CRM Online Spring ‘14. While it continues to work, it doesn’t represent the best practices to use with queues in the most recent release. More information: Enhancements to queues with CRM 2013 service pack 1 (on-premises) and CRM Online Spring ‘14

Sharing queues is no longer the preferred way to make them available to other users. Public queues are available to all users and access to private queues is set by using AddPrincipalToQueueRequest.

Requirements

For more information about the requirements for running the sample code provided in this SDK, see Use the sample and helper code.

Demonstrates

This sample shows how to give a team limited access to a queue. A queue is shared, and a team is given full access to the queue items, such as create, delete, retrieve, and update. However, they can only retrieve a queue.
