Sending email from plugins

Hi There,

We have tried using the inbuilt email routing from within CRM but the overall admin of the site is not under our control and we're having some issues trying to get the person responsible to sort it out.

As an alternative we're wanting to use the System.Net.Mail library to send emails from within plugins but we're getting some issues. Specifically with the following error message when we send:

Request for the permission of type 'System.Net.Mail.SmtpPermission, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

We've tested the code locally in a test app so we know it works. I was wondering if there is something with Dynamics CRM that prevents us from sending out emails by this means or if there is something that I would need to configure to allow it through.

We're using Dynamics CRM 2013 online.

Many thanks

Dan

    You are blocked from accessing non HTTP/HTTPS resources from sandboxed plugins in Dynamics CRM, and some parts of the .NET framework are also not accessible - see msdn.microsoft.com/.../gg334752(v=crm.6).aspx

    If you really can't get the Email Router configured (although this is the best practice method of sending emails from CRM) you will need to create an external webservice that you call from your plugin to send out emails.

    Hope this helps,

    Scott
