This is an unsupported customization, where we would be hiding the account option from the convert lead dialog box.
For doing so,
Find and open the conv_lead.aspx page on your crm server.
Inside the function window.onload add the following code
function window.onload( )
{
// add the following line of code to hide the checkbox
document.getElementById('cbAddAccount').style.display ='none';
and to hide the label by commenting out the following tag
<label for="cbAddAccount">
<% =Microsoft.Crm.CrmEncodeDecode.CrmHtmlEncode(Util.GetFmtObjName
(Util.Account, Util.NameFormatStyle.Singular)) %></label>
Just remember this is unsupported.
Or use the following JavaScript
document.getElementById(‘cbAddAccount’).style.display = “none”;
document.getElementById(‘cbAddAccount’).parentNode.parentNode.childNodes[1].childNodes[0].style.display = “none”;
Bye.

Hi,
I was able to debug the plugin when registered in asnychronous, child pipeline on post create of contact ( from lead conversion box)
Have you attached your debugger to both w3wp.exe and CrmAsyncService?
Try by restarting CrmAsyncService and then attaching the debugger to it.
Let me know about it !

What is the event/message name for converting an e-mail to a case? I need to register a plugin on this event before the e-mail is converted to a case.
