In a workflow activity I am taking the "ResourceParent" from an Expected Rule entry. From this user, I am getting the GUID from the manager field. This value I return as workflow parameter. The next step in the workflow is to send an email notification. Here I send it to the guid that I found in the activity. I have logged the workflow parameter, which correctly returns a guid for a user, which is mail enabled. But the workflow tries to send the notification it gets the following error: Microsoft.ResourceManagement.Service: System.ArgumentException: Invalid or NULL email address at Microsoft.ResourceManagement.Mail.Utilities.ValidateMailMessage(GenericMessage message, IMailServer mailServer) at Microsoft.ResourceManagement.Mail.NotificationMessage.Send() at Microsoft.ResourceManagement.Workflow.Hosting.SendMailWorkItemProcessor.SendMailMessage(MessageContent messageContent) at Microsoft.ResourceManagement.Workflow.Hosting.SendMailWorkItemProcessor.ProcessWorkItem(WorkItem workItem) Any ideas?

Are you passing the Guid as a Guid or as a string? The EmailNotificationActivity takes a string for it's To property and trying to pass it as a Guid may fail. //HenrikHenrik Nilsson, ILM/FIM MVP Blog: http://www.idmcrisis.com Company: Cortego (http://www.cortego.se)

I have tried both ways, but I get the same error. /Søren

It definitely a problem resolving the email address from the Guid and I can't come up with a good idea why except maybe the format of the Guid isn't accepted after being converted into a string. A solution could be to resolve the email yourself by using a ReadResourceActivity...Henrik Nilsson, ILM/FIM MVP Blog: http://www.idmcrisis.com Company: Cortego (http://www.cortego.se)

Hi Sylle, Is the portal user synchronized with an AD user? i had a similar problem where the email field was empty because the user wasn't synchronized... Hope this helps...

I have seen this error in the past when the object in the portal doesn't have the 'email' attribute value in the portal populated. The manager may have a proper email address in AD but is it available in the portal? If not, try putting correct value in it and attempt.
