exchange 2013 - SSL certificate issue for all clients




I had exchange 2013 installed on Windows 2012 server and all way happy until I attempted to add remote access role. This failed the first time, and I had to remove the role and re-add the role. Remote Access is working fine, however, I now have a very annoying issue with every PC on the network not being able to confirm the SSL certificate.
When outlook connects, and tries to set up the profile, we get an error like this:



enter image description here



Now this is the same error (but just a random google image) I have to then view the certificate and install on any machine and the end users certainly cannot cope with this. It used to work all nicely.



How can I fix this please?



I had to re-apply ssl certificates in IIS, and I suspect this is where the issue lies - can I reset all certificates?



Answer



Here is what I did to fix the issue.





The last post shows how to get the certificate and then deploy via group policy.



All tested and working OK.
