Outlook 2016 - the name on the security certificate is invalid
Posted on 2016-08-23
We have just installed a new windows 2012 server running 2 hyperv servers. One being our domain controller and the other being our exchange 2016 server.
We have this working OK apart from the SSL certificate integration. ie we were getting complaints on starting up outlook regarding an invalid or untrusted certificate. I presumed that once we obtained the correct SSL, this would just disappear.
Unfortunately, having just purchased our True ID SAN from geotrust, and installed it, we are still experiencing a warning on starting outlook. This is :-
The name on the security certificate is invalid or does not match the name of the site.
I have spoken with geotrust and they tell me its because it is looking for the internal exchange 2016 name, which I can confirm is the case.
the name of the local server is exch2016.domain.local
Our SSL is to secure remote.domainname.co.uk and autodiscover.domainname.co.uk
Geotrust say that we have to rename our local site to match??
Can anyone advise on what we need to do to resolve this problem?
