Exchange cert expired how do I renew cert

On my Exchange 2007 sever running on a 2008 Server I go into IIS and see the cert expired, users also get the cert expired notification when they open Outlook. What is the best way to renew this? It's a cert that was issued from the server, not a third party.

Hi there,

you can do this by running the following command

1. Get-ExchangeCertificate -thumbprint “expired-cert-thumbprint” | New-ExchangeCertificate

You can get the thumbprint by running a Get-ExchangeCertificate first

2. afterwards, you can verify that by running

Get-ExchangeCertificate -thumbprint “new_cert_thumbprint” | fl

If you right-click on the default web site and select properties it will bring up the properties. Then click on security (I think) and View Certificate. This will confirm that the cert has definitely expired. If it has, you need to buy a new one or request a renewal depending on who provided your previous cert. You can do that from the same place but the method you use will differ depending on how you renew your certificates. I always select 'create request now but send later' then copy the request to my SSL Cert provider who send the response.

@cjimail2k I'm not using a third party. The expired cert was issued by the exchange server.

I notice to the right in IIS it give me the option to
- create certificate request
- complete certificate request
- create domain certificate
- create self-signed certificate

I believe the first two are used for 3rd party certs, am I right about this? Do I want to create a self-signed cert? I don't believe I'm interested creating a Domain cert.

Sorry,

what you could/should do as well is enable that certificate for the corresponding services by using the Enable-Certificate cmdlet as well.

And maybe next time I will upload a doc without client information.
Does anyone know how to remove an embedded doc or do I need to create my ticket? :)
