IMAP-Verbindung zu Outlook C# OAUTH@ ⇐ C#

[Guest]

Gibt es einen Grund, warum ich keine Verbindung zum IMAP-Server Outlook herstellen kann? Ich verwende MailKit Lib

Ich verbinde mich so:

Code: Select all

else if (settings.Protocol.Equals("IMAP"))
{
try
{
var protocolLogger = new ProtocolLogger("imap-log.txt");
using (var client = new ImapClient(protocolLogger))
{
await client.ConnectAsync("outlook.office365.com", 993, SecureSocketOptions.SslOnConnect);
//mail look like this  [email protected]
await client.AuthenticateAsync(new SaslMechanismOAuth2(settings.ClientLogin, result.AccessToken));

var a = client.Inbox.Open(FolderAccess.ReadWrite);
await client.DisconnectAsync(true);
}

}
catch (Exception ex)
{

}
}

mit dem Bereich „https://outlook.office365.com/.default“ oder „https://ps.outlook.com/.default“ funktioniert beides nicht. Irgendwelche Ideen, warum ich nicht auf IMAP zugreifen kann?
Ich habe alle Privilegien

Update, ich habe mich einmal mit IMAP verbunden, Danach wurde immer noch ein fehlerhafter Benutzer authentifiziert, aber keine Verbindung hergestellt :
