I was creating a second website for additional owa/ecp vdirs (see - https://social.technet.microsoft.com/Forums/office/en-US/04222fae-8f13-4ef3-b3b8-b699d7e547af/exchange-2013-multiple-iis-owa-sites-with-different-authentication?forum=exchangesvrclients&prof=required

Simply created a new website in IIS, and makde a copy of the OWA and ECP folders in C:\Program Files\Microsoft\Exchange Server\V15\FrontEnd\HttpProxy.  2nd website works fine

HOWEVER, now when trying to log into  OWA (default web site) - I get "This page could not be displayed.Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to https://exservernam.domain.com"?  If I go directly to that server and launch owa(https://localhost/owa), I can get into owa fine (just not from other computers (https://servername/owa

The supported method is :

DId you follow that?

Yes, that is what I did to create the second site. The second site works fine...........it's all the vdirs under the Default Web Site that give the above error

Got this working again - thought I would post in case someone else runs into this.

When I looked at the default bindings for the default web site, there were 2 entries for 443 - one with the typical 127.0.0.1, and one for "all unassigned".  When I looked, the one with "IP Address *" (all unassigned) did not have the certificate listed under SSL Certificate" (In IIS, Defrault Web site,  site bindings, choose the htttps 443 * binding, edit, then go to SSL Certificate).  Assigned the certificate there, and was able to hit all my vdirs under Default Web Site again.

Hi,

Thank you for your share.
