Yesterday I installed the updates that Microsoft had released. Unfortunate as it looks like OWA, ECP and Outlook stopped working after this installation. See picture for the updates were made.

What you are greeted by when besker OWA and ECP is a blank page. Is anyone had the same problem and knows how to fix this?

Or is there a way to back these updates?

You can uninstall them I suppose, but before you do that, check that all the Exchange Services are running and server component health is good

Get-ServerComponentState <server>

Anything in the event logs? Server rebooted?

Have you checked IIS logs for user connectivity errors? Have you rebooted the server(s)? Restarted IIS? Is the blank page before or after authentication?

I think i have more then one problem...

What OS version, what Exchange version are you running? Have you rebooted the machine(s)? As Andy asked, any logs in event viewer? We need a few more details. Have you tried launching EMS from another server? How many machines were these updates installed on?

The problem is this error can arise for many different reasons. Check your bindings for a certificate under the website hosting these virtual directories.

Hi Jesper,

Is there any update? Have the issue been resolved?

The updates are all for Windows server 2012 R2. What's your Exchange server version? Additionally, please check the following in IIS Manager:

a. In IIS manager > Default Web Site, make sure Anonymous Authentication is Enabled in Authentication.
b. Double-click SSL Settings, confirm that "Require SSL" is checked on the root of the default website.
c. Restart IIS service by running iisreset /noforce from a command prompt window.

If possible, please collect more event logs in Event Viewer for further analysis.

Regards,
