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.
