Hi All,
Just created simple workflow to achieve this functionality....here is code in case some one needs it..
[CrmWorkflowActivity("Remove the Email from the Queue")]
public class RemoveEmailFromQueue : System.Workflow.Activities.SequenceActivity
{
//Email Id Property
public static DependencyProperty activityIdProperty = DependencyProperty.Register("activityId", typeof(Lookup), typeof(RemoveEmailFromQueue));
[CrmInput("ActivityId")]
[CrmReferenceTarget("email")]
public Lookup activityId
{
get { return (Lookup)base.GetValue(activityIdProperty); }
set { base.SetValue(activityIdProperty, value); }
}
//Queue Id Property
public static DependencyProperty queueIdProperty = DependencyProperty.Register("queueId", typeof(Lookup), typeof(RemoveEmailFromQueue));
[CrmInput("queueId")]
[CrmReferenceTarget("queue")]
public Lookup queueId
{
get { return (Lookup)base.GetValue(queueIdProperty); }
set { base.SetValue(queueIdProperty, value); }
}
//output Property
public static DependencyProperty resultProperty = DependencyProperty.Register("result", typeof(string), typeof(RemoveEmailFromQueue));
[CrmOutput("result")]
public string result
{
get { return (string)base.GetValue(resultProperty); }
set { base.SetValue(resultProperty, value); }
}
/// <summary>
/// Execute Method of Workflow
/// </summary>
/// <param name="executionContext"></param>
/// <returns></returns>
protected override System.Workflow.ComponentModel.ActivityExecutionStatus Execute(ActivityExecutionContext executionContext)
{
try
{
IContextService contextService = (IContextService)executionContext.GetService(typeof(IContextService));
IWorkflowContext context = contextService.Context;
// Obtain IcrmService so we can call into CRM SDK to retrieve
ICrmService crmService = context.CreateCrmService();
// this property will have the email address that needs to be matched.
string strEmailGUID = activityId.Value.ToString(); //"305c2ecb-c26b-de11-9ba7-0003ff2b38e4";
// this property will have queue that needs to be matched
string strQueueID = queueId.Value.ToString();// "D0B55822-436A-DE11-8911-0003FF2B38E4";
DetachFromQueueEmailRequest objEmail = new DetachFromQueueEmailRequest();
// Assign Email GUID
objEmail.EmailId = new Guid(strEmailGUID.Trim());
// Assign Queue GUID
objEmail.QueueId = new Guid(strQueueID.Trim());
//execute request to removed it from queue
DetachFromQueueEmailResponse response= (DetachFromQueueEmailResponse)crmService.Execute(objEmail);
this.result = "Success";
return ActivityExecutionStatus.Closed;
}
catch(Exception ex)
{
return ActivityExecutionStatus.Canceling;
}
}
}
