When you launch the Microsoft Dynamics CRM Email Router Configuration Manager, you receive the following error:

"Email configuration manager was not able to read configuration information."


The Microsoft.Crm.Tools.EmailAgent.Configuration.bin located at C:\Program Files\Microsoft CRM Email\Service is corrupted or is 0 KB in size.


Use one of the following resolutions to resolve this error.

Resolution 1:  Repair or reinstall the Microsoft Dynamics CRM Email Router.

Resolution 2:

  1. Delete the Microsoft.Crm.Tools.EmailAgent.Configuration.bin located at C:\Program Files\Microsoft CRM Email\Service.
  2. Restart the Microsoft Dynamics CRM Email Router service.
  3. Now launch the Email Router Configuration Manager. A new Microsoft.Crm.Tools.EmailAgent.Configuration.bin will be created, and a blank configuration will appear.
  4. Configure all the profiles and the deployments.

If Microsoft Dynamics CRM users are set to use the Email Router, and not a Forward Mailbox, for incoming email, there is a possibility of deleted emails returning to Microsoft Dynamics CRM after implementing this resolution. If an email has not been deleted from the user's mailbox, the Email Router could find a user's email in their Inbox, not find it in Microsoft Dynamics CRM, and create the email in Microsoft Dynamics CRM again. To avoid this, the email should also be deleted from the user's mailbox along with Microsoft Dynamics CRM.

To avoid this situation, 
 regularly take a backup of the following files and store them on the desktop of the same server.

  • Microsoft.Crm.Tools.EmailAgent.Configuration.bin
  • Microsoft.Crm.Tools.EmailAgent.SystemState.Xml

If the Microsoft Dynamics CRM Email Router Configuration Manager fails at launch or the Microsoft Dynamics CRM Email Router service fails to start, replace the above 2 files in C:\Program Files\Microsoft CRM Email\Service. Restart the Microsoft Dynamics CRM Email Router service and then launch the Microsoft Dynamics CRM Email Router Configuration Manager. If the back up of these files is latest, then it will have the complete configuration of the Email Router.
