We are experiencing issues with accessing ECP on Exchange 2016 from specific networks.
We have IP restrictions set in IIS under ECP and have added the IP addresses of the new network we upgraded at one site which hasn't helped. Our old network at other locations can access ECP without any issues.
There are no errors and the sign in page refreshes after entering the credentials.
IIS logs show: 302 0 0 156 at the end.
Where can I find detailed/advanced logs for ECP logins to Exchange Server 2016.
Any leads would really help.
Thanks!
