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 &quot;'No CRL Found' Error Message Even When CRL Is in Cryptdlg.dll&quot; 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 You may receive one of the following error messages if you try to verify a certificate that has been revoked and is on the certificate revocation list (CRL) that is downloaded by a CRL Distribution Point (CDP):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 Under some circumstances, the certificate may still get checked by using the CDP as if the certificate has not been revoked, which causes the error message.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. For additional information, click the article number below to view the article in the Microsoft Knowledge Base:

Retrieve LDAP Certificate Through Levels of Certificate Chain
The &quot;OL2000: Retrieve LDAP Certificate Through Levels of Certificate Chain&quot; article describes the following problem. Outlook 2000 is not able to navigate a Certificate Distribution Point (CDP) through multiple levels of a certificate chain after retrieving a certificate from a Lightweight Delivery Access Protocol (LDAP) server. This fix is included with Office 2000 Service Pack 2.

252365 OL2000: Retrieve LDAP Certificate Through Levels of Certificate Chain

The Lightweight Directory Access Protocol (LDAP) service for Outlook 2000 Corporate Workgroup (CW) does not support Secure Sockets Layer (SSL) for secure connections. This fix is included with Office 2000 Service Pack 2. For additional information, click the article number below to view the article in the Microsoft Knowledge Base:

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.
