Reissue Exchange 2010 certificate without "internal names"

Hi,

I am in the process of reissuing our exchange certificate without internal names (like suggested in that Digicert blog).
https://blog.digicert.com/exchange-replacing-internal-names-certificates-part-2/#prerequisites

Is it correct that I have to change the Client Access Array’s URL (from the local FQDN to a public FQDN) to match the public name in the certificate? I’m not a 100% sure if it is necessary.

Thanks
Joerg

Hi

Yes will need to change it as your internal clients are likely connecting to the internal URL which won't match the security certificate name and cause them to get an error on their outlook clients.  Users that are working externally connecting over https using the external FQDN will not see an issue...

I have used this article many times to carry out the changes post certificate change to external names only.  Just replace as applicable - https://support.microsoft.com/en-us/kb/940726
