Our SSL certificate recently expired and was renewed but Outlook 2010 Clients are still getting SSL errors. We use Exchange 2010. We use DNS to point to our external certificate and have the following in place to cater for that:
Set-ClientAccessServer -Identity CAS_Server_Name -AutodiscoverServiceIntern
ctory -Identity "CAS_Server_Name\EWS (Default Web Site)" -InternalUrl https://mail.contoso.com/ews/exchange.asmx
Our Outlook Web Access is getting the correct certificate and it seems to be only affecting our internal clients. When I run the Get-exchangeservercertific
ate command the correct certificates are in place. The old certificate is not visible anywhere yet I still get the error. I have even checked the registry and also under MMC but cannot find the reference point for the old certificate anywhere. Can anyone help?
