| Description | Failed to read attribute <attribute name> from Active Directory for <user name>. |
| Event Information | Explanation : This event indicates that attribute msExchUserAccountControl is not set or it is set incorrectly on a user object in Active Directory. If you are working in a mixed-mode environment where Exchange 2000 or Exchange 2003, and Exchange Server 5.5 are installed in separate Active Directory domains, when you try to grant permissions that are granted to public folders on the Exchange 2003 computer to a mailbox that is homed on the Exchange Server 5.5 computer, you receive Event ID 9562. This issue can occur because any user object that is mailbox-enabled must have the msExchUserAccountControl attribute stamped on it by the Recipient Update Service, and the attribute value must be set to 0. If the user object is not configured in this way, it is treated as mailbox-disabled. By default, Recipient Update Service is not available in an Active Directory domain that has only an Exchange Server 5.5 computer. Therefore, the user object in Active Directory that is associated with the mailbox on the Exchange Server 5.5 computer does not have the msExchUserAccountControl attribute set. When you add a mailbox on the Exchange Server 5.5 computer to permissions that are granted to a public folder in Exchange 2000, the information store on the Exchange 2000 computer assigns the distinguished name of this mailbox to that public folder. The Exchange 2000 information store tries to upgrade this Exchange Server 5.5 distinguished name to a Windows 2000 security identifier (SID). If the Active Directory user object that is associated with this mailbox does not have the msExchUserAccountControl attribute set, when the information store reads this attribute, and then fails to upgrade the Exchange Server 5.5 distinguished name to a Windows 2000 SID, the information store generates Event ID 9562.
