GoDaddy Cert reissue for Exchange 2010

HI! I have tried to research this scenario and cant get my expiring cert renewed. Any help would be greatly appreciated!. I have tried to import the new cert and renew the cert. I get an error " certificate thumbprint already exists" when I click complete pending request and point it to the new cert. I had also imported the intermediates cert through GoDaddy instructions.. I am stuck at this point and wondered if anyone could give me any help.

I would suggest creating a new certificate request from EMC. Then take that request to godaddy with the request and then complete the request once you get it back from godaddy.

You typically get that message if the certificate is installed under the personal certificates on the server. Remove it from there any try again.

When I create a new request and paste the key into the ssl cert on GoDaddy's page it recreates the same named cert. I end up with the same thumbprint error.
Did you remove the old cert from the Personal certificates store on the server? You can do that from a snap-in (certmgr.msc)
I do not see the pending request cert under the personal store. I see the other certs we have as well as the expired one that I am trying to replace. Should I remove the expired cert I am trying to replace?
Yes, remove the expired cert from the Personal Store. It shouldn't have been in there in the first place. It should be in the Trusted Root Certification Authorities folder in a 'Certificates' folder.

Lastly, note that you typically only have 90 days to renew an expired certificate after which you have to process an entirely new certificate.
It has been less than 1 month since the expiration. I have removed the expired cert in from "Personal". Installed the intermediate and then went to process pending request for the renewed cert and I get the thumbprint error again. What am I missing?

Thank you for your time and patience!
Check IIS and make sure that it is removed from there as well.
Looked at server certs in IIS and the expired cert is not in the list.
Should I remove pending request and try to install a New Exchange Cert?
try to remove the request and then add the cert without the request pending. I think i have ran into that once before but it might be a long shot.
It can't hurt. You can also try searching through the rest of the Certificate Store to see if you can find the cert that matches that thumbprint.
If I search under thumbprint I only get the "Pending request " cert I just implemented. This was after I removed it and created a New Exchange Cert.
Did you try to remove the pending request and import the new cert?
Yes I removed it and then added a new one.
ah what i mean is to remove the request for the new cert. Then take the already completed cert from godaddy and try to import it. So your not completing a request your just importing the cert.
You can also remove the cert from the command line - you need to start a command window with Admin priv.

Syntax is: Remove-ExchangeCertificate -Thumbprint whateverthethumbprintis
Upon import is asking for a pw for the private key. How can I obtain this .. through GoDaddy?
Not sure why you'd be getting asked for that. You would only assign a password to a certificate if you were doing an export to move the certificate to another machine. How are you trying to import this renewal cert? Through the EMC?
Yes in EMC. If I click Import Exchange Certificate it asked for the cert file and underneath that there is a pw field. It says that you must enter the password of the private key on import.
In the EMC you should be navigating to Server Configuration, right clicking your server, then choosing 'Complete Pending Request'. Then you browse to the location of the downloaded CSR file.
This cert was for a subdomain we issued through the server sometime ago. I followed the directions here: http://it.mzedan.com/2012/07/18/certificates-for-exchaneg-2010-using-internal-ca/
The problem I am having now  is that the cert is not showing up under pending in the EMC. I went to personal cert folder and trusted root and selected the certs and retried to no avail.
I'm confused now. I thought you were renewing a GoDaddy cert? Those guidelines you linked to are for a self-generated certificate.

At this point it might make sense to simply issue a new clean GoDaddy UCC certificate. Good writeup on the whole process here: https://support.godaddy.com/help/article/5863/installing-an-ssl-certificate-in-microsoft-exchange-server-2010?countrysite=www&marketid=en-US
We had one GoDaddy that had expired, it was not for our subdomain access sorry for the confusion
Just go buy an SSL cert and go through the toturial.. does it matter at all that is is "remote.mydomain.com" ?
