Hello All-I recently used selfssl to install a certificate on a new Exchange 2007 server (CAS, Hub, MB). After this, Outlook clients began receiving security alerts, and autodiscover seems to be hosed. I'm even having issues connecting new users to exchange, which I think is related.My question, is how can I go about restoring the original certificate that is deployed with Exchange 2007??? Thanks in advance!!

You can remove the current cert, http://technet.microsoft.com/en-us/library/aa997569.aspx then createa new cert, http://technet.microsoft.com/en-us/library/aa998327.aspx. No way to get back the original cert.

Johns second link get extra dot which make it cannot be reached http://technet.microsoft.com/en-us/library/aa998327.aspx Herere some more references may help: How to create Exchange 2007 self signed certificates How to check your current configuration of certificates: Get-ExchangeCertificate | fl > c:\currentcert.txt How to add services to a certificate: Enable-ExchangeCertificate -thumbprint "............" -services POP3
