title: Dynamics CRM 2011 E-mail Router error: e-mail address is not associated with any approved forward mailbox user or queue record in CRM
body: <p>I am trying to create an email-to-case workflow that converts e-mail messages sent to support mailboxes into CRM cases, but the e-mail router fails to process certain messages during validation (according to the MSCRMEmailLog file). Instead of entering the queue as e-mail activities (which the workflow converts to cases), they pop up as errors in the server's Event Viewer. I have reviewed the numerous posts about e-mail router issues (<a href="http://social.microsoft.com/Forums/en-US/8e3da5fb-7088-439a-81ee-1eff6515c9e9/crm-2011-ru4-email-address-is-not-associated-with-any-approved-forward-mailbox-user-or-queue?forum=crmdeployment" rel="nofollow noreferrer">external users</a>, <a href="https://community.dynamics.com/crm/b/crmmayankp/archive/2012/05/02/crm-2011-email-router-issue.aspx" rel="nofollow noreferrer">queues pending approval</a>, and <a href="https://stackoverflow.com/questions/7611868/dynamics-crm-2011-e-mail-router-exchange-2010-cluster-error-incoming-status">account credentials</a>), but none of the solutions have fixed my e-mail routing error.</p>
  
  <p><strong>CRM System Settings</strong> <br>
  <em>E-mail</em>: (Selected) Process e-mails only for approved users &amp; approved queues. <br>
  <em>Queues</em>: 5 total. Each mailbox address is approved and Incoming/Outgoing options are set to E-mail Router for All e-mail messages. The System Administrator is the owner of each queue.<br>
  <em>Tracking</em>: (Selected) Track e-mails sent between CRM users as two activities.</p>
  
  <p><strong>E-mail Router Configuration Settings</strong> <br>
  'Status: Succeeded' for incoming &amp; outgoing messages for all Users &amp; Queues listed for the deployment. 'Status: Succeeded' for all 5 forward mailboxes.</p>
  
  <p><strong>Other details</strong><br>
  (1) We are using the Visendo SMTP Extender on the server to monitor an e-mail drop folder from which the e-mail router picks up the e-mails.<br>
  (2) Sender e-mail addresses associated with CRM (user, queue, etc.) and not associated with CRM result in this error.</p>
  
  <p>Any help would be appreciated.</p>
