Hallo,

ich habe das Problem, dass bei uns das Autodiscover seit kurzer Zeit nicht mehr richtig funktioniert.
Exchange wird nur Online genutzt. Das hat auch alles funktioniert.
Jetzt bekommt man aber über Outlook keine Verbindung mehr, wenn man ein neues Konto verbinden möchte. Alle schon verbundenen Postfächer funktionieren. Der DNS Eintrag für das Autodiscover wurde natürlich gesetzt und, der funktioniert auch.
Der Test auf: https://www.testconnectivity.microsoft.com schlägt leider auch fehl. Leider komme ich mit den Fehlermeldungen bisher nicht weiter. Das Benutzerkonto, welches ich bei dem Test angegeben habe funktionier auf jeden Fall und ist auch nicht gesperrt.
Das einzige, was mit einfällt, ist, dass vor kurzem unserer Homepage auf HTTPS umgestellt worden ist. Aber kann das so ein Problem hervorrufen?
