is it possible capture sending email status outlook add-in c#

Question

I have ApplicationEvents_11_ItemSendEventHandler email sending event, but this event in email sending status is always false, so any event capture email sending is true or false.

Answer 1

Do you mean MailItem.Sent is still false? This is to be expected. The very first time you can access the sent message is when Items.ItemAdd event fires on the Sent Items folder. By then Sent property will be true and all the sender related properties will be populated.
