Proxy mit Authentication

Mein Internet Explorer/Internet Settings sind eingestellt, der Browser kommt auch problemlos an externe Adressen. Ich meine mich aber zu erinnern, dass bei jeder Erstverbindung das Passwort angefragt wird, diese Frage bleibt bei Nutzung aus Outlook aus. Vielleicht wichtig:Outlook nutzt den Proxy bisher gar nicht, weil lediglich interne Mailboxen angefragt werden.

es sollte eigentlich schon lange mit den standard Einstellung von Windows gehen, d.h. die Einstellungen, die man mit IE/Edge vornimmt, werden vom .NET framework für Outlook DAV dann genommen

Hallo zusammen,

anbei nochmal als Wiedereröffnung zu einem früheren Thread im alten Forum. Es ging damals um das Problem, dass mein PC sich hinter einem Internet Proxy befindet, bei dem zur Nutzung eine Anmeldung erforderlich ist. Outlook DAV kann hierbei keine Verbindung zum Server herstellen, vmtl. weil es die Credentials nicht abfragt bzw. sich nicht vollständig des System Proxys bedient. Anbei nochmal das Tracefile, nachdem die E-Mail dazu scheinbar irgendwo versackt ist.

Code:
