Aspose.Email Get Undelivered Messages

Hello,
I am evaluating Aspose.Email componet. Is there any way to get undelivered messages from Exchange using EWSClient?
I found old solution on forum
ExchangeQueryBuilder builder = new ExchangeQueryBuilder();
builder.ContentClass.Equals(“REPORT.IPM.Note.NDR”);

but there is no more ContentClas property on ExchangeQueryBuilder . Is there any other way?

Please read the following article to achieve your requirement. The ExchangeQueryBuilder.ContentClass property exists in Aspose.Email APIs.
