Hi Lukas,

Some days back, you gave us below code for resolving issue while accessing a large mailbox account. In this code, first we are fetching all messages in "ImapMessageCollection ids" using imap.Search() method. And then again we are setting as per chunk size ImapMessageSet. After this again we are doing imap.GetMessageList() and fetching the messages. Aren't we doing repetitive actions? Please explain.

    private ImapMessageCollection ImapSearch(Imap imap, ImapSearchParameter imapSearchParameter)
    {
        try
        {
            // search for messages, receive only Unique ids
            ImapMessageCollection ids = imap.Search(ImapListFields.UniqueId, imapSearchParameter);

            // get only necessary information in small chunks
            ImapMessageCollection messages = new ImapMessageCollection();

            for (int i = 0; i < ids.Count; )
            {
                if (i > 0)
                    System.Threading.Thread.Sleep(DELAY_TIME);

                ImapMessageSet set = new ImapMessageSet();
                for (int j = 0; j < CHUNK_SIZE && i < ids.Count; j++, i++)
                {
                    set.Add(ids[i].UniqueId);
                }

                ImapMessageCollection list = imap.GetMessageList(set, ImapListFields.Envelope | ImapListFields.Body);
                foreach (ImapMessageInfo info in list)
                {
                    messages.Add(info);
                }
            }

            return messages;
        }
        catch (Exception ex)
        {
            logger.Error(string.Format("Error Occured at ImapSearch. Error :{0} ", ex));

            throw ex;
        }
    }
