exchange certificate

I have an existing wildcard certificate created for one of my remote desktop servers can I use that same certificate on my exchange 2007 server or do I need to generate a request first? My wildcard certificate was purchased from Rapid SSL and is in a .pfx container

Import-ExchangeCertificate -Path "C:\CertificateFile.pfx"

Enable-ExchangeCertificate <thumprint> -Services:"IMAP, IIS, POP"

and for Outlook Anywhere wildcard support

Set -OutlookProvider -Identity EXPR -CertPrincipalName *

If it fails will I loose any existing connectivity? I am currently using an expired self generated cert which is stopping me for using outlook Anywhere with Outlook 2013

You can migrate it with the keys to your Exchange server. You would also want to enable the certificate for SMTP services as well.

If it fails, clients will receive certificate errors.

If you already have the certificate, then no need to do a new request.
On the existing server, export the certificate using the Certificates Management Console. Make sure that you include the private key as well. If the SSL provider has also given you root/intermediate certificates you will need to import those with the wizard as well.

You cannot use the result file from the provider - you need to export it fresh.

Connectivity will not be lost once you make the changes required. They don't take full effect until you restart the IIS services.
