We purchased a new certificate and installed it in Exchange Server. All external clients can access Exchange Server very smooth. However, some internal Outlook will pop out a message when users start up the Outlook:
This message will not appear until the computer (Windows 7 / Windows 10) reboot and start up again.
Our external exchange URL : exchange.fcasia.com
Internal exchange URL : exchange.fcasia.com
AD domain : asa.net
Exchange Server : HKEXCHANGE01, HKEXCHANGE02, HKEXCHANGE03
DAG IP : exchange.fcasia.com / IP: 172.16.10.21
I checked the Outlook connection status, it seems that the connection is correct:
I checked the internal autodiscover URL and also run nslookup to check the autodiscover.fcasia.com
Get-ClientAccessServer | select id,AutoDiscoverServiceInternalUri
In Exchange Server virtual directory:
OWA, EWS,ECP,OAB : internal and external URL is https://exchange.fcasia.com
Can anyone help to solve this issue?
