Hello Dale,
Thanks for using Microsoft Newsgroup Support Service, my name is Ji Zhou
[MSFT] and I will be working on this issue with you.
Firstly, I want to ensure I understand our objective correctly. We are
trying to identify if an email is forwarded or written and sent directly
from the sender, right? If I have misunderstood, please feel free to let
me
know.
Based on my research, I do not find a consolidated way to achieve this
objective. There is a tool Outlook Spy that can be used to view a mail
item's all object model properties, as well as all the property tag
values.
I use it to look through a forwarded mail item from bottom to top on my
side, but nothing contained in the mail item tells the exact information
we
want to know. Consequently, I think this may be not possible. I have also
consulted the product team to confirm this. If I get their reply, I will
let you know as soon as possible.
However, may I suggest to judge if the property tag PR_SUBJECT_PREFIX's
value is "FW: " and then perform the corresponding action in our Outlook
Add-in. The code will look like. We can get more information about the
PropertyAccessor and the property tag list from the following two links,
http://msdn.microsoft.com/en-us/library/bb176395.aspx
http://msdn.microsoft.com/en-us/library/ms526356(EXCHG.10).aspx
private void button1_Click(object sender, RibbonControlEventArgs e)
{
Outlook.MailItem mail =
Globals.ThisAddIn.Application.ActiveInspector().CurrentItem as
Outlook.MailItem;
object subjectPrefix =
mail.PropertyAccessor.GetProperty(@"
http://schemas.microsoft.com/mapi/propta
g/0x003D001E");
if (subjectPrefix.ToString() == "FW: ")
{
Debug.Print("This email is forwarded and the default subject prefix
is not modified");
}
else
{
Debug.Print("This email may be not forwarded");
}
}
I mention this way because outlook will use the default prefix "FW: " when
a user tries to forward a mail to others. This is not a very good
workaround since it cannot catch the emails whose whole subjects are
modified by the senders. But hope it will help more or less.
If you have any future concerns or questions, please feel free to update
this thread, and I will try my best to follow up. Have a great weekend!
Best regards,
Ji Zhou (
