[Exchange 2016] Update naar CU6 geeft OWA error 500

[Operations]

Ik heb onze Exchange 2016 willen updaten naar CU6.
De update opzich is goed verlopen.
Na het installeren kan ik niet meer inloggen via OWA, ik krijg dan error 500. De ECP doet het wel.

Nu ben ik de eventvwr in gedoken, en zag ik dat de thumbprint niet meer correct was. Dat heb ik opgelost via:
https://social.technet.mi...te?forum=exchangesvradmin

Die error is nu ook verdwenen, ik blijf nu zitten met error 1309:

Dit zou dan komen omdat SharedWebConfig.config in de C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess niet bestaat.

Die heb ik aangemaakt via:
https://support.microsoft...p-after-you-install-excha

Alleen nu blijft die error terugkomen, terwijl ik ook fysiek het bestand zie staan.

Toen kwam ik nog een website tegen die aangaf deze map C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\owa leeg te gooien, en de mappen opnieuw zelf te laten genereren door opnieuw in te loggen op de OWA. Heeft helaas ook niet geholpen.

Iemand enig idee? Beetje overbodig misschien maar voor de CU6 update werkte OWA uiteraard wel.

Deze mag dicht, als je eerst met een half oog naar engels voetbal kijkend .NET framework 4.7 installeert op de Exchange server dan gaat dit uiteraard problemen geven. Iets met wijze les en 1 ding tegelijk doen

@Operations Mooi zo
