SYMPTOMS
You may get the following error when you try to encrypt and/or sign messages:

Unable to obtain a valid certificate revocation list. Digital signatures cannot be trusted at this time.



CAUSE
The Key Management (KM) Server can not write the certification revocation list to the directory. This happens when the KM Server service account is not set correctly.



RESOLUTION
Make sure the service account for the KM Server is the Microsoft Exchange service account.
