Exchange 2013 OWA blank white page - Certificate Problems

In case you get a blank white page after successful login to OWA or ECP, maybe one of your certificates is expired. Try this:

Open as Administrator a command shell:

netsh http show sslcert

Open an editor and paste the information from the output above - you'll need it later for lazy cut and paste..

Delete the expired certificate:

netsh http delete sslcert ipport=0.0.0.0:444

You should get somethink like "SSL Certificate successfully deleted"

Now open MMC with Plugin "Certificates". Go to the new valid certificate and grep the Thumbprint. Cut and paste just works using an editor.

Assign the new certificate:

netsh http add sslcert ipport=0.0.0.0:444 certhash=XXX  ppid=“{YYY}“

Now reset IIS:

iisreset /stop

iisreset /start

I hope you are so lucky as I was!
