"The certificate is invalid for exchange server use" error message on previously working certificate
This error has just appeared.
This certificate was working absolutely fine and has been for about a month or so. All of a sudden a customer called in saying that the certificate was being rejected(? I've gotten this message about 3rd hand so don't know exactly what it said I'm afraid) and looked on the exchange console and was met with a big red X. I've re-imported the certificate trusted authority to the correct place.
Just puzzle how to fix as it hasn't expired and was working fine a day ago.
