Fixes in Office and Internet Explorer
The following articles describe fixes included Office 2000
service packs.
'No CRL Found' Error Message Even When CRL Is in Cryptdlg.dll
The "'No CRL Found' Error Message Even When CRL Is in
Cryptdlg.dll" article describes the following problem. You may receive one of
the following error messages if you try to verify a certificate that has been
revoked and is on the certificate revocation list (CRL) that is downloaded by a
CRL Distribution Point (CDP):
No CRL found.
-or-
The CRL is unavailable or expired.
These
error messages can occur in programs such as Outlook 2000 that can use
certificates. The error message is returned as expected. Under some
circumstances, the certificate may still get checked by using the CDP as if the
certificate has not been revoked, which causes the error message.
This fix is included in Internet Explorer 5.01 Service Pack 2 and Internet
Explorer 5.5 Service Pack 1. This is scheduled to be included with Internet
Explorer 5.5 Service Pack 2.

Certificate Information from the Recipient Is Not Added
After you right-click a resolved recipient e-mail address,
certificate information from the recipient is not added to the contact if you
click
Add to Contacts or
Personal Address Book. This behavior can occur because neither the Personal Address
Book nor the
Add to Contacts commands adds certificates if
they are not in the preferred certificate property. The certificate is not
accessible from an LDAP server in some configurations. This fix is included
with Office 2000 Service Pack 2.
