Common Exchange 2007 Errors
Wildcards on Exchange 2007
Though Wildcards are compatibile with Exchange, they can cause issues with POP3 and IMAP. For more information, see our page on Exchange 2007 Widlcard compatability.
Private Key Missing
Error message: "The certificate with thumbprint... was found but is not valid for use with Exchange Server (reason: PrivateKeyMissing)."
Exchange admins sometimes get this message when they are unable to complete a task. For a complete description and workarounds, see our Exchange 2007 private key missing error page.
Outlook Error Connecting to Exchange
Error message: "The name of the security certificate is invalid or does not match the name of the site."
For general information, see our page about name mismatch in web browser errors. However, you may also want to check if Outlook is attempting to connect to Exchange via an internal name. If it is, make sure that the internal name is listed as a Subject Alternate Name in your SSL Certificate.
Duplicate SAN Names
Error message: "The value xyz is already present in the collection."
When creating the Exchange 2007 CSR command make sure that no names are duplicated.
Service Not Installed
Error message: "Service is not installed."
This error may happen when you run the Enable-ExchangeCertificate command from the Exchange Power Shell command line and one of the services for which you are attempting to enable your certificate is not installed.
The easiest way to fix this is to remove the service from your command and run it again. However, if you need to have that service, install/configure the service and then run the command again.
