ListMessages() agains IMAP server always return 0

My code

ImapClient imapSource = new ImapClient();
imapSource.Port = 993;
imapSource.Host = xxxx;
imapSource.Username = xxx;
imapSource.Password = xxx
ImapFolderInfoCollection folderInfoColl = imapSource.ListFolders();
foreach (ImapFolderInfo folderInfo in folderInfoColl)
ImapFolderInfo folderInfoStatus = imapSource.GetFolderInfo(folderInfo.Name);
Console.WriteLine("Total Messages: " + folderInfoStatus.TotalMessageCount);
ImapMessageInfoCollection msgInfoColl = imapSource.ListMessages(false);
Console.WriteLine("Total Messages: " + msgsColl.Count);

The first information “folderInfoStatus.TotalMessageCount” return the correct number of messages, but the second information “msgsColl.Count” is always 0 (also if I try for another folder)
I try against OBM server ([https://www.obm.org ](https://www.obm.org/))
If I try against gmail, I haven’t this kind of problem

What is the problem ? How can I solve it ?



We are unable to reproduce this issue so can you please provide sample account on OBM server for further investigation?

Here is my code

    static bool RemoteCertificateValidationHandler(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
        return true; //ignore the checks and go ahead

    static ImapClient GetSslClient()

        ImapClient imap = new ImapClient(
        new RemoteCertificateValidationCallback(RemoteCertificateValidationHandler)
        return imap;

            ImapClient imapSource = GetSslClient();

            IImapMessageInfoCollection messageInfoColl = imapSource.ListMessages();
            int nbmessage1 = messageInfoColl.Count;
            ImapFolderInfoCollection folderInfoColl = imapSource.ListFolders();
            int nbfolder1 = folderInfoColl.Count;

            messageInfoColl = imapSource.ListMessages("Inbox");
            int nbmessage2 = messageInfoColl.Count;
            folderInfoColl = imapSource.ListFolders("Inbox");
            int nbfolder2 = folderInfoColl.Count;


In Inbox folder, there is one message
I expected to get following informartion
nbmessage1 = 1
nbfolder1 = 7
nbmessage1 = 1
nbfolder1 = 7

I retrieved
nbmessage1 = 0
nbfolder1 = 1
nbmessage1 = 0
nbfolder1 = 7

Two problems
Why don’t I get messages ?
Why the first call of ListFolders retrieve only one folder (inbox) and not sub folder of inbox ?
