if (entity.LogicalName == "incident")
{
ColumnSet attributes = new ColumnSet(new string[] { "description" });
Entity entty = service.Retrieve(entity.LogicalName, entity.Id, attributes);
if (entty.Contains("description") && entty.Attributes["description"] != null)
{
String desc = entty.Attributes["description"].ToString();
String desc2 = StripHTML(desc);
entty.Attributes["description"] = desc2;
service.Update(entty);
}

    Vetrivel,

    Don't get me wrong - I'm not paid for replying and doing everything I asked on forums. I'm here for providing directions and suggestions and not doing someone's other job. Either do you job and write the code or be more specific with your questions like I've done this and I experienced this issue.

    Also if my reply/replies answered your question (as far as I understood I helped you to resolve your initial issue) take a minute and click "Yes" under question "Did this answer your question?" at the top of reply/replies.

    It seems there are missing or extra closing brackets - }. Go through your code and fix it.

    RE: Converting html to plain text Plugins

    Hello,

    According to your screenshot you handle "Create" message of email.

    According to your code you perform changes for incident.

    That's obvious contradiction - re-register your plugin to handle "Create" message for "incident" and you're good to go.

    One more thing I want to mentioned - there is no need to read and update the record when your code works as pre-operation plugin. Here is an easy fix that will remove unneeded retrieve/update:

    if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
{
Entity entity = (Entity)context.InputParameters["Target"];

try
{
if (entity.LogicalName == "incident")
{
var description = entity.GetAttributeValue("description");
if (string.IsNullOrEmpty(description)){
return;
}

description = StripHTML(description);
entity["description"] = description;

}

catch (Exception ex)
{
throw new InvalidPluginExecutionException("An error occured in the Plugin:-", ex);
}

}

}
