Exchange 2013 Powershell ECP dosen't Work, Receive Error loading....
Help me so much, this is a common issue when replacing the Exchange 2013 Certificate.
Solution to solve it is to replace the certificate for 0.0.0.0:444 with the correct one. For some reason one of the certificates is being used instead of the one that is being served on standard https port.
Click Start, point to All Programs, click Accessories, right-click Command Prompt, clickRun as administrator, and then click Continue.
Type netsh http show sslcert, and then press ENTER to view the installed certificates.
This will show the certs. Make a copy of the output to safe place.
Under IP:port 127.0.0.1:443 note the certificate hash and application ID.
Type netsh http delete sslcert ipport=0.0.0.0:444 (do this command even if the port doesn’t exists on the list), and then press ENTER to delete the incorrectly installed certificate.
netsh http add sslcert ipport=0.0.0.0:444 certhash=<noted_hash> appid=”<noted_appid>”, and then press ENTER to reinstall the certificate.
That’s it. After rebooting certificate should be in it’s place and content from Exchange being served correctly.
Note : I didn't reboot the server and it still worked for me, i would try not rebooting before.
