Hello i have renewed Exchange 2007 self singed certificate using the following commands and it was successful. 1. Get-ExchangeCertificate |FL 2. Get-ExchangeCertificate –Thumbprint “OLD THUMBRPINT” | New-ExchangeCertificate 3. Enable-ExchangeCertificate – Thumbprint “NEW THUMBPRINT” –Services IIS 4. Remove-ExchangeCertificate –Thumbprint “OLD THUMBPRINT” QUESTION : My exchange2007 is not connected to internet. Users first time when they access OWA they have to install certificate. Is there anyway which i can push the certificate on the client pcs so that they need not install certificate at all and it should be trusted becoz some of my users are not so intelligent.
