Can't access OWA page in Microsoft Edge or IE11 RRS feed

  • Question

  • Fresh install of Exchange Server 2016 Standard
    SSL certificate is configured and setup.

    When attempting to access the OWA page from either Edge or IE11 i get the error:

    Can’t connect securely to this page
    This might be because the site uses outdated or unsafe TLS security settings. If this keeps happening, try contacting the website’s owner.

    Loading the page in Chrome or Firefox presents no errors. Loading the page in IE on the server itself works fine.

    I have checked the SSL and TLS settings in the Advanced menu in Internet Options on the workstation i'm viewing it on and everything is correct. We've tried several workstations and they all present the same message.

    Any ideas?

  • The issue ended up being an HTTP Proxy issue on our firewall. We added the domain as an exception for the content filter and the OWA now loads in IE11 and Edge correctly.

    It appears as though those browsers use different protocols than Chrome or Firefox.
