Hi, Im getting an error when attempting to download envelopes from a folder.

This is the error
The server has responded with negative reply. The server responded: MBN00000004 NO The specified message set is invalid..

Code

     //open the bounced welcome email folder on the server
                      imapServer.SelectFolder(settings.WelcomeEmailFolderName);


                      //get the envelopes for all the emails in the folder
                      _log.Debug("Retrieving messages from mail server.");
                      EnvelopeCollection envelopes = imapServer.DownloadEnvelopes(Imap.AllMessages, false);

                      if(envelopes.Count <= 0){
                           _log.Info("No messages found in mail folder.");
                           return;
                      }

Any ideas on how to resolve this would be greatly appreciated.

Thanks,
Jesse

I would suggest checking imapServer.MessageCount property prior to calling DownloadEnvelopes method. If there are no messages in selected folder, some mail servers might reject an attempt to download envelopes.

Yes, it appears that the error was occurring when there were no messages in the folder. I didnt see any examples indicating this needed to be done. Checking the count first resolves the problem.

Thanks.
