Trying to renew Exchange 2007 self-signed certificate

Posted on 2014-08-14

I have a client who called and said they are getting certificate warnings in Outlook now.  They run Exchange Server 2007 on SBS 2008.

I ran "Get-ExchangeCertificate |FL", and among many entries, some expired some not, I got this (server name changed):

AccessRules        : {System.Security.AccessControl.CryptoKeyAccessRule, System
                     .Security.AccessControl.CryptoKeyAccessRule, System.Securi
CertificateDomains : {Sites, COMPANYSERVER.server.local}
HasPrivateKey      : True
IsSelfSigned       : False
Issuer             : CN=companyserver-SERVER-CA
NotAfter           : 09/08/2014 2:20:35 PM
NotBefore          : 09/08/2012 2:20:35 PM
PublicKeySize      : 2048
RootCAType         : Registry
SerialNumber       : 17A81F11000000000008
Services           : IMAP, POP, IIS, SMTP
Status             : DateInvalid
Subject            : CN=Sites
Thumbprint         : A8F19ACED13801B4B8D1111783B13BFD21ED3D2D

They told me they had a self signed certificate, but this says, "IsSelfSigned : False"

How to I proceed to renew this so that people aren't getting warnings when they run Outlook etc.? (The email system in question is very small - just half a dozen users, low volume of mail)

    Accepted Solution


    Open the SBS Console> Networking Tab > Connectivity.

    Run the Fix My Network wizard on the right hand side.  This should find that the certificate needs renewing and resolve it for you.
