After you deployed the CRM 2011 on premise and the CRM e-mail router you may experience a problem when loading data from Email Router Configuration manager.

Issue 
When you hit the “l(fā)oad data” button on the “User, Queues, and Forward Mailboxes” Tab in the Email Router Configuration manager …

… the e-mail router might not be able to load the data. Within the  CRM platform trace the below error can be seen: 

On the UI the following error will be reported: 
 

Cause 
The e-mail router expects a HTTPS connection to the CRM website and if SSL is not enabled on the website the request will fail.

Workaround 
Add the registry key "DisableSecureDecryptionKey" on the CRM Server. If you configure the value to 1 the email router configuration manager will explicitly check for HTTP.

1. Click Start , click Run , type regedit , and then click OK . 
2. Locate and then click the following registry key: 

3. On the Edit menu, click New , and then click DWORD Value . 
4. Set the name of the subkey to DisableSecureDecryptionKey . 
5. Right-click DisableSecureDecryptionKey, and then click Modify . 
6. In the Value data box, type 1 in the Value data field, and then click OK . 
7. On the File menu, click Exit .
