SYMPTOMS
When a Microsoft Outlook user connects to a mailbox that is on an Exchange 2000 Server computer, the user may receive the following error message:

Unable to update public free/busy data. Could not complete operation. One or more parameter values are not valid.



CAUSE
This problem can occur if the legacyExchangeDN attribute for this user in Active Directory has distinguished name (DN) delimiters (for example, /O, /OU, /CN) that either use all uppercase letters (for example, /O=ORG NAME/OU=SITE NAME/CN=RECIPIENTS/CN=AD USERS/CN=USERS/CN=USER NAME) or partial uppercase letters (for example, /O=ORG NAME/OU=SITE NAME/cn=RECIPIENTS/cn=AD USERS/cn=USERS/cn=USER NAME). The legacyExchangeDN attribute changes to all uppercase letters when you use Exchange System Manager or the Mbconn.exe support tool to reconnect a mailbox to an associated Active Directory account. The reconnect process erroneously sets the DN delimiters to uppercase letters.

The legacyExchangeDN attribute is used for backward compatibilty with components that are earlier than Exchange 2000 to represent the way that a DN was stored in the Exchange Server 5.5 directory. Some components and programs have not been updated to use the Active Directory-style DN, so those components and programs rely on the legacyExchangeDN attribute to provide the Exchange Server 5.5-style DN.
