UC Certificate Stopped working after Upgrade

Ok I have upgraded Exchange to service pack three. However now my UC Certificate has stopped working all together.

Options
1. Should I start from scratch and re generate them from godaddy.
or
2. Should I try to re enable the UC Certificate using the following command ?

Enable-ExchangeCertificate -Thumbprint paste_thumbprint_here -Services "SMTP, IMAP, IIS"

My problem here is I am unsure on the correct thumbprint as I get the following when I run
Get-ExchangeCertificate

I am learning towards starting over on the UC Certificate but I really don't know what option to try. Any advice would be great,

Thanks.

- You need to reenable it. Using Enable-ExchangeCertificate -Thumbprint paste_thumbprint_here -Services "SMTP, IMAP, IIS"

How do I know which thumb is the correct Certificate though ?

Suliman Abu Kharroub

When you open outlook, do you get a security warning message ? when you click view the certificate, id it the correct certificate ?

Also, check the Certificate store on exchange server from MMC. do you have the correct certificate stored there ? if so, just re-assign services to certificate and restart exchange services.

Enable-ExchangeCertificate -thumbprint <certificate-thumbprint> -services "IIS,POP,IMAP"

Suliman Abu Kharroub

Use the Get-ExchangeCertificate cmdlet to determine the thumbprint for your certificate.
