Hi guys,


I just bought an SSL certificate for our Exchange server. Everything works fine as people can log on to web emails now and use Outlook Web App.

However, now people's machines are coming up with a certificate error (attached). It's an internal name! Can I create a self signed one? And if yes, then where would I put it?

Value your help guys

No. Stick with the 3rd party cert.

My guess is that when you renewed it dropped your ability to renew the internal names of the server? If so, you may have internal FQDNs configured on your internal URLs. I am not sure which version of Exchange you have but I would recommend checking out these two articles for configuring split-DNS and reconfiguring your internal URLs.

Hey Gareth

Thank you man. I'm running Exchange 2010 SP2.

I just went back to the certificate supplier and managed to revoke the old one and re-implement a new one and it permitted me to make additions like ...name.uk.fc.local.

The only issue is I've assigned and completed the ssl install of the one previously. If I wanted to go down that road of getting this SSL applies, do I have to start all over again and start from scratch?
