After following this guide: https://acbrownit.com/2014/04/04/exchange-autodiscover-episode-2-attack-of-the-exchange-server/
My internal Outlook clients can't connect to Exchange 2013 server. I was trying to get rid of a certificate error because of the DOMAIN.local not being included in the certificate.
I only changed ServiceBindingInformation attribute from:
https://autodiscover.DOMAIN.local/autodiscover/autodiscover.xml
to:
https://autodiscover.DOMAIN.com/autodiscover/autodiscover.xml
Since then, I've reverted back hoping it would resolve the issue with the internal Outlook clients but nothing changed. OWA is having issues too. After logging in, the page, 'Something went wrong' comes up.
Any help is much appreciated.
