SSRS: Render your reports in HTML4.0 instead of MHTML!

By default in SQL Server 2012 (Enterprise) when you create a new data-driven subscription (DDS), you’re able to select ‘HTML4.0‘ as a rendering format. But when you create a normal subscription, the option isn’t available.

SSRS 2012 HTML4 subscription


Here’s how you can enable the functionality of rendering in HTML4.0 format for a normal subscription. Please remove Visible=”false” for the HTML4.0 rendering extension in the RSreportserver.config file as follows:

<Extension Name="HTML4.0" Type="Microsoft.ReportingServices.Rendering.HtmlRenderer.Html40RenderingExtension,Microsoft.ReportingServices.HtmlRendering" Visible="false"/>

To get the HTML4.0 to be included in the body of the email rather than as an attachment, look for this element in the RSreportserver.config file:

< EmbeddedRenderFormats>

And add this as an extra entry within that element:


In my own file the whole thing now looks like this:

< EmbeddedRenderFormats>

This works fine for me using SQL 2008 R2 and up.

Also for SQL Server 2016, the option for HTML5 is also available (same principle as above). But in SQL 2016 with HTML5 it was still send as an attachment instead of embedded. So somehow the embed-config doesn’t work properly yet?
