I am trying to resolve a stubbed email but the message body does not appear.
The POA calls the ReadItemRequest() of the archive webservice.
To resolve the stubbed mail I tried the following:

Mail mail = new Mail();
mail.Subject = "Subject";
string text = "Message boy text.";
List<MessagePart> messages = new List<MessagePart>();
MessagePart mpart = new MessagePart();
mpart.Value = Encoding.UTF8.GetBytes(text);
mpart.contentType = "text/plain";
mail.Message = messages.ToArray();

return new ReadItemResponse(mail, new Status(0, "", ""));
With larger message bodies (>16k) and the following ReadAttachmentRequest() I am abled to
restore the mail body. The Groupwise program version is 8.0.2.

Thanks in advance.
