MS CRM 2011: Strange error during sending of an email from plugin

I had scenario when my plugin based on some condition had to send an email. I developed plugin, deployed it to server and during the testing I have got quite strange error:

Message was generic and hasn’t explained what happened. I’ve downloaded log file which had following text:
Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: An unexpected error occurred.Detail:

This log also didn’t explaine anything and I went to Trace:

I understood that this specific exception was generated not with my code but with CRM core operation – Sending of am email. I remain that about a year ago I faced and solved similar issue with tasks.

My habit is to instantiate IOrganizationService in plugins using system account:

IOrganizationServiceFactory factory = 
    (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
IOrganizationService service = factory.CreateOrganizationService(null);


I have changed instantiation of service to running user and everything worked without any issues:

IOrganizationServiceFactory factory = 
    (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
IOrganizationService service = factory.CreateOrganizationService(executioncontext.UserId);


I hope that this topic will help other developers to solve their issue faster then I solved it.
