I have a lot to learn about certificates and hope I can learn here. The issue is with Outlook only on external networks connecting to SBS2008. When users open Outlook they are prompted with a Security warning stating that certificate is invalid or has expired. More details show that it has expired. We do not have an issue with RWW and I can see the cert.
It seems we are using two GoDaddy standard SSL certs and the one that Outlook tries to use is the one that recently expired. Issue didn't pop it's head until it expired. The other one installed on server is working for RWW/OWA only.
Services for the current cert are: IMAP, POP, IIS, SMTP
How can I get Outlook to use the cert that is current and already installed or is that not the issue?
I probably don't have enough info posted here but will answer anything I can.
Thanks for your help.
