Hi,

How do I retrieve a list of undelivered emails using your API?

Hi Mark,

Thank you for writing to us.

I think you want information about retrieving messages that couldn’t be delivered. I have checked this with various messages and would like to share with you that Undelivered messages have contents class equal to “REPORT.IPM.Note.NDR”.

Please have a look at the following example that retrieves all such messages from an Exchange Server using EWS. It uses ExchangeQueryBuilder to retrieve a list of all such messages. Please feel free to contact us if you need further assistance in this regard.

ExchangeWebServiceClient client = GetExchangeClient();
ExchangeMailboxInfo exchangeMailboxInfo = client.GetMailboxInfo();
ExchangeQueryBuilder builder = new ExchangeQueryBuilder();
builder.ContentClass.Equals("REPORT.IPM.Note.NDR");
MailQuery query = builder.GetQuery();
ExchangeMessageInfoCollection msgInfoCollection = client.ListMessages(exchangeMailboxInfo.InboxUri, query, true);
foreach (ExchangeMessageInfo msgInfo in msgInfoCollection)
{
    MailMessage mailMsg = client.FetchMessage(msgInfo.UniqueUri);
    //Do the required work with mailMsg
}

Hi Kashif,


That certainly helped me. Thank you.

However, when I try to get the original “To” field from the retrieved undelivered messages, it doesn’t work. Can you help in this? I want to get a list of all undelivered messages and retrieve the original email address to which the email was sent to.
