The way that code is written you would get that event handler garbage
collected and fail to fire at some point. Declare and instantiate an Items
collection at module or class level and hook your ItemAdd() handler to that
so your handler doesn't get garbage collected.

In ItemAdd() you are passed an Item object. Cast that to a MailItem object
and then use string replace function to get rid of the unwanted text.
Something like this would do it, add exception handling of course:

Outlook.Mailitem mail = (Outlook.MailItem)Item;
string newBody = mail.Body.Replace("My Special Sentence", "");
mail.Body = newBody;

If you are getting syntax errors be specific on what and where, if you want
help with them.

VSTO C#, OL2007

I want to remove the phrase "My Special Sentence" from every email after
it gets sent and appears in the Sent Items folder.

I started, finding the following code on the internet but being new to C#
and VSTO I have had some difficulties with syntax errors with it.

using Outlook = Microsoft.Office.Interop.Outlook;
defaultFolder =
this.Session.GetDefaultFolder(Outlook.OlDefaultFol ders.olFolderSentMail);
defaultFolder.Items.ItemAdd += new
Microsoft.Office.Interop.Outlook.ItemsEvents_ItemA ddEventHandler(SentItems_ItemAdd);

Can anyone help me with some code to remove the phrase "My Special
Sentence" from every email after it gets sent and appears in the Sent
Items folder.

TIA
