Hi, You can renew self signed certificates using the command Get-ExchangeCertificate | New-ExchangeCertificate http://smtpport25.wordpress.com/2009/06/17/exchange-2007-self-signed-certificate/ Regards, Krishna| MCSE:M|MCTS:M http://smtpport25.wordpress.com/

Yes, Self signed certificate has host name with their own NetBios and FQDN names only so it doesn't require to change anything for other server's certificate.Amit Tank | MVP Exchange Server | MCITP: EMA | MCSA: M | http://ExchangeShare.WordPress.com

The problem will happen if we dont renew that certificate you posted above NotBefore : 7/7/2008 1:14:33 AM It seems that the certificate will expire tomorrow
