This policy setting allows you to treat Level 2 errors as warnings instead of errors. Level 2 errors occur when the message signature appears to be valid, but there are other issues with the signature.
If you enable this policy setting, Level 2 errors will be treated as warnings.
If you disable or do not configure this policy setting, Level 2 errors will be treated as errors
When you specify a value for PromoteErrorsAsWarnings, note that potential Level 2 error conditions include the following:
- Unknown Signature Algorithm
- No Signing Certification Found
- Bad Attribute Sets
- No Issuer Certificate found
- No CRL Found
- Out-of-date CRL
- Root Trust Problem
