Hi All,


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
Id           AutoDiscoverServiceInternalUri
--           ------------------------------
HKEXCHANGE03 https://exchange.fcasia.com/Autodiscover/Autodiscover.xml

HKEXCHANGE01 https://exchange.fcasia.com/Autodiscover/Autodiscover.xml

HKEXCHANGE02 https://exchange.fcasia.com/Autodiscover/Autodiscover.xml


c:\nslookup autodiscover.fcasia.com
Server: HKDC01.ASIA.NET
Address: 172.16.10.1
Name:  autodiscover.fcasia.com
Address: 172.16.10.21


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?


Best Regards,

Thomas
