Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client.

Hello, I am using Microsoft Dynamics Nav 6.2 Classic (32bit), installed on windows server 2008 R2, I have a problem in sending email from Navision, I always receive the error :"Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client."

I checked my outlook and it's set as default mail client. I have Microsoft Professional Plus 2010, Outlook Version 14.0.4760.1000 (64-bit). I googled this error and non of the method (such as fixing the registry of outlook) could solve this error.

Any help please.
