Outlook - Name on the security certificate is invalid or does not match the name of the site

Once the cert has been installed you will need to enable the cert. Can be done EMC.

When i go into Outlook i get the following error:

outlook01

This is because i’m connecting to services using the NetBIOS name of mbx1 which does not match the name on the certificate. If i run Get-ClientAccessServer -Identity Server | fl i’ll see that the AutoDiscoverServiceInternalUri says https://mail.server.com/Autodiscover/Autodiscover.xml, this does not match the certificate. I can also check the other services and see that i get the same results for OAB, EWS, Outlook Anywhere (OA) and Exchange Active Sync (EAS). So i need to update all theses internal url’s to match the name on the cert.

  • Set-ClientAccessServer –AutodiscoverServiceInternalURI https://remote.server.com/autodiscover/autodiscover.xml

 

  • Set-WebServicesVirtualDirectory -Identity "server\EWS (Default Web Site)" –InternalUrl  https://remote.server.com/EWS/Exchange.asmx

 

  • Set-OABVirtualDirectory -Identity “server\OAB (Default Web Site)” -InternalURL https://remote.server.com/OA

 

  • Enable-OutlookAnywhere -Server mbx1 -ExternalHostname “remote.server.com” -ClientAuthenticationMethod “NTLM”
  • Set-ActiveSyncVirtualDirectory -Identity “server\Microsoft-Server-ActiveSync (Default Web Site)” -InternalURL https://remote.server.com/Microsoft-Server-Activesync

Sometimes you have mail.doman.com in the DNS (internal or external). If the namr not in use, please delete the record,
