Mixed Exchange Server ECP portal not accessible
Your detailed reply was very helpful in my review.
The following servers are using self-signed certificates:
VOH-SOU-VM-EX1
VOH-SOU-VM-EX6
[Action Item]
Ensure that all Exchange servers use the same publicly trusted SSL certificate.
In the IIS Manager Console, unify the SSL binding settings for “Default Webs Site” and “Exchange Back End” with a public certificate!
Thank you for the information you sent.
After review, there are no missing arbitration mailboxes, which is normal.[Action Item]
To execute these PowerShell scripts, follow these steps,
Open PowerShell as administrator and use the ‘cd’ command to navigate the Exchange ‘Bin’ directory.
For instance,
cd “C:\Program Files\Microsoft\Exchange Server\V15\Bin.”Then execute the following commands to run the PowerShell scripts to fix the configuration issues.
.\UpdateConfigFiles.ps1
.\UpdateCAS.ps1This may take a while to finish.
Once done, restart the server and check if the HTTP 500 error is resolved and ECP/EAC is accessible.I would like to know the result value of the following execution.
Get-Mailbox -Arbitration
- Thanks for reply.
I understood.
Please try iisreset at the Exchange Server 2016. If you have a load balancer, make sure it is configured properly.
Once the Exchange 2013 server is activated, everything seems to work,
so this could be related to the load balancer settings or health checks.
