DOCUMENT:Q170911 23-OCT-1999 [exchange] TITLE :XADM: Clean Mailbox Utility Deletes Msgs Not Archived PRODUCT :Microsoft Exchange PROD/VER:winnt:5.0 OPER/SYS: KEYWORDS:kbusage exc5 ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Server, version 5.0 ------------------------------------------------------------------------------- SYMPTOMS ======== When you use the Clean Mailbox utility in the Microsoft Exchange Server Administrator program, modified messages are deleted unexpectedly. CAUSE ===== Every message has properties that track time properties of the message, such as the delivery time of a message and the time the message was last modified. The Clean Mailbox utility in the Microsoft Exchange Server Administrator program determines the message age on the basis of the MAPI property PR_MESSAGE_DELIVERY_TIME, that is, the date the message was received. However, Outlook auto-archive determines message age on the basis of the MAPI property PR_LAST_MODIFICATION_TIME, that is, the date the message was last modified. This difference may result in problems. For example, if you plan to auto- archive messages after they reach a certain age, and you then delete messages using the Clean Mailbox utility, some messages may be deleted that have not yet been auto-archived because the last modification date may be changed. For information about how might the last modification date be changed, please reference the following article in the Microsoft Knowledge Base: Q161808 Message Modification Date Determines Archive Date STATUS ====== Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.0. This problem has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 5.0.
