Adding X-Protective-Marking "Peter" <palace[ at ]internode.on.net> 2/21/2007 5:47:18 AM Greetings I am a newbie so please be gentle:-) Am using OL2003, VSTO 2005SE with VS2005 (VB.NET) I have managed to create an addin using VSTO a toolbar with dropdown on a new mail message that adds a security classification to the subject line before the mail is sent. What I am also trying to do is add a custom header (X-Protective-Marking:) to the mail message before it is sent. I can't easily see how to do this. Any help or pointers so other examples would be greatly appreciated. Cheers Peter Lock Palace Software

A CDO sample to create an x-header is shown in a custom form at http://www.ivasoft.biz/addheader3.html. -- Ken Slovak [MVP - Outlook] http://www.slovaktech.com Author: Absolute Beginner's Guide to Microsoft Office Outlook 2003 Reminder Manager, Extended Reminders, Attachment Options http://www.slovaktech.com/products.htm "Peter" <palace[ at ]internode.on.net> wrote in message news:eFseAvXVHHA.4796[ at ]TK2MSFTNGP05.phx.gbl...
