asked on 

Exchange ECP log-in loops back to log-in after entering credentials.

Greetings.
I recently updated our SSl certificate on Exchange 2016.
Upon ding so, I lost connectivity to my ECP portal.
All I get when I login in is a reloop back to login again.
I have tried checking the certificate and settings but they look good as per my understanding.
I am not an Exchange Guru and this is the first time I encountered this issue.
I do need this resolved so I can add new users to our environment.
I could do it from our other Exchange Server in the DAg, but I do not want to go that route.
Reason being is that the issue will still be there: relooping after attempting to login.
I do can use OWA but not ECP.
I am running windows 2012 R2 as the OS for Exchange 2016.

I checked the settings in "default website" the bindings and they are correct pointing to the correct certificate.
I restarted the service on IIS in application pools called "MSExchangeECPAppPool", but to no avail.

Thank you for your attention.

Saif, thank you for your response.
So I should confirm that the settings from binding from my "exchange backend website" settings should match the "Default website"?

yes even if you have a valid self-signed cert binded to exchange backend then its fine, but you can keep the same third party doesn't matter.

Therefore both should match identically?

NONNONONO

Click on edit 443 on default website and you should see a view tab and there you will be able to see the cert.

Also click on edit 444 on backend website and you should see a view tab and there you will be able to see the cert.

Do not attempt to change any ports, just see if port 443 on default website and port 444 on exchange backend has the correct cert.

Saif, thank you.
I added the correct cert on the ports for exchange backend server.
Afterwards I restarted the IIS services/server.
Once that completed, I know have access to my ecp.

I will have to put this in my notes for when I have to update the cert again in years time from now.

Thank you for your assistance.
