Get Email Message using Exchange webservices without attachment, using C#

[ewanc1]

I am getting emails from a mailbox using exchange webservices using a custom code block in C# (I’m not versed in C# at all so forgive code quality!). I am passing the exchange service and folder ID as arguments to the code block. I noticed that when there was a large attachment on the email it took significantly longer. I am not interested in the attachment I just want to be able to access some information about the email. This was my initial code:

//Search for oldest email 
ItemView objView = new ItemView(1);
objView.OrderBy.Add(ItemSchema.DateTimeReceived, SortDirection.Ascending);
FindItemsResults<Item> lstItems = objServer.FindItems(in_FolderID, objView);

//Bind to email from result
if(lstItems.Count() == 0) 
{
    Console.WriteLine("Inbox appears to be empty");
    out_ExchangeMessage = null;
    out_InternetMessageID = null;
}
else
    {
        Item objItem = lstItems.ElementAt(0);
        Console.WriteLine("Retrieving email: " + objItem.Subject);
        PropertySet objPropertySet = new PropertySet(BasePropertySet.FirstClassProperties, ItemSchema.MimeContent, EmailMessageSchema.IsRead,ItemSchema.Attachments,ItemSchema.TextBody);
        out_ExchangeMessage = EmailMessage.Bind(objServer,objItem.Id, objPropertySet);
        out_InternetMessageID = out_ExchangeMessage.InternetMessageId;
        Console.WriteLine("Message Retrieved: " + out_ExchangeMessage.InternetMessageId);
    }

I tried removing ItemSchema.Attachments so this line reads as follows. But the email still takes significantly longer to download, so feels like it is still getting the attachment.

PropertySet objPropertySet = new PropertySet(BasePropertySet.FirstClassProperties, ItemSchema.MimeContent, EmailMessageSchema.IsRead,ItemSchema.TextBody);

Is there a way to speed up the retrieving of emails with large attachments?
