I have renewed a Godaddy UCC cert and reran the certificate wizard in SBS2008 and choose the renew option. All went trhough fine, however I am still getting the following errors in the event log:
The STARTTLS certificate will expire soon: subject: remote.xxxx.co.nz, hours remaining: 6D31915688B026136632A300DFE44EF99DFD368F. Run the New-ExchangeCertificate cmdlet to create a new certificate.
I've verified from a remote office that the certificate has in fact now got the correctly renewed expiry date as shown in Internet Explorer.
