Saving MailItem after adding user properties nulls body

Question

I am running into an odd scenario when modifying the mail item on a reply/reply all.  In my integration I am adding some custom user properties to a message as it arrives to the inbox.  When that message is issued a reply, I need to copy those properties/values to the new response message. The properties get added and set with no problem, but when I call mailItem.Save() on the response item, the Body property of the response item gets nulled out.  To workaround this , currently I am resetting the body/htmlbody before the save is issued.  If I do this, then the body is not nulled out on the save.  Any idea(s) why this would happen? Am I doing something wrong in the order in which I am doing things.  I basically get the response mail item from the reply/replyall event, set user properties/values and then issue a save, when I do this the body is null.

Thanks in advance for any input, much appreciated.

Hi Craig,

Welcome to MSDN forums!

As my understanding, you question is if you save any user property programmatically when replying a message, the message body will be blank when it sent, right?

I'm trying to narrow down this problem, as you said this is odd, so, would you please provide us some additional information about your softer environment? Which Version of Outlook is involved? Which version of VSTO are you working on?

In your message I saw you connect this two behavior "mailItem.Save()" and "Body/HTMLBody nulled out", do you mean if you comment out the save method and the problem goes away?

If it's possible, please provide some code snippet for us to reproduce issue, or have a more clear view on it.

Looking forward to your feedback.

Thanks.

Using Visual Studio 2008 SP1, VSTO 2007, C#

Sorry for the late response. If I bypass the calling of the save everything is normal.  It is when I set the custom property values and issue the mailitem.save() that the body is set to null.

For example:

private void SetUserPropertyValueImpl(string propertyName, object propertyValue)

{

            ItemProperty property = GetUserProperty(propertyName) ??

                                   _mailItem.ItemProperties.Add(propertyName, OlUserPropertyType.olText, true, System.Reflection.Missing.Value);

//put a break point here, put a watch on teh _mailItem.Body

         _mailItem.Save();

//put another break point here, the body will be null.

}

 public ItemProperty GetUserProperty(string propertyName)

        {

            foreach (ItemProperty property in _mailItem.ItemProperties)

            {

                if (property.Name == propertyName)

                    return property;

            }

            return null;

        }

Any luck reproducing this issue, curious.  Also this is happening on the reply/reply all or forward event.
