This article will fix your OWA ECP "This page can't be displayed" error.
Today I had a customer with OWA and ECP was not opening. It returned the error shown below. This error normally happens when the certificate binding is not correct. The steps shown below will help you clear this issue.
Open IIS Manager and open binding of
Default Web Site.
Right-click
Default Web Site and click on
Edit Bindings...
Please make sure the required bindings are there. I noticed one binding is missing. To add the missing binding please follow the instructions shown below.
Open the site binding window of
Default Web Site again and click on
Add.
Please ensure you have configured the binding settings as shown below and then click on
View to ensure you have selected the right certificate to bind.
When you click
V iew you will get a popup like this to make sure you selected the right certificate.
Once you selected the right certificate click on
OK.
You will see a new binding as in the following screenshot. Click
Close.
Reset IIS using the following command.
iisreset /noforce
Now you will see your OWA and ECP working.
