You can use the 3rd party certificate for all the services. Its just a matter of assigning all the services to it. (SMTP, IIS, POP, IMAP)

Hello, I use Exchange 2007 and have a SelfSigned certificate on my Hubcas"1" which expire soon with the following services: IMAP, POP, SMTP and a third Party SAN certificate. I have the same certificates on my Hubcas"2" except that my SelfSigned certificate will expire in may 2012 and has the following Services: SMTP I pretty much know how to renew my SelfSigned certificate: Get-ExchangeCertificate | where {$_.IsSelfSigned -like "True"} | fl Get-ExchangeCertificate -Thumbprint XXX | New-ExchangeCertificate Enable-ExchangeCertificate – Thumbprint XXX –Services ....... And here is the question: Which services should I enable on my SelfSigned certificate? I notoce a difference between my 2 SelfSigned certificate on my both HUBCAS. How do I know which services are needed? Also and as I have a thrid party certificate, would it be possible not to user the SelfSigned certificates ? If I do not renew them what would happen? Many thanks in adavance. Graig
