XADM: Event ID 1151 and 1154 Are Logged When You Move a Mailbox

When you move a mailbox from one Exchange 2000 Server-based computer to another, the following events may be displayed in the Application log of the Event Viewer:

Event ID: 1151
Event Source: MSExchangeIS Mailbox
Event Type: Warning
Event Category: Rules
Event Description:
A rule synchronization error (1144) has occurred on Mailbox Store "storename"
The mailbox folder is Top of Information Store\Inbox
The distinguished name of the owning mailbox is ---.
There are 24 of 24 retries remaining.

Event ID: 1154
Event Source: MSExchangeIS Mailbox
Event Category: Rules
Event Description:
Rule synchronization has successfully completed.
The mailbox folder is Top of Information Store\Inbox on database "database name".
The distinguished name of the owning mailbox is /O=organization/OU=organizational unit/CN=Recipients/CN=s140605.

However, the mailbox move operation completes successfully, and you experience no loss of functionality with the mailbox on the destination server.

This behavior may occur after you have increased the level of diagnostics logging on the Exchange 2000 Server mailbox store. These notification events do not indicate a problem with the moved mailbox, and are not logged at the default diagnostic logging level in Exchange 2000 Server.

This behavior is by design.

When you move a mailbox, the mailbox rules are packed in a single package on the source server, and are then moved to the destination server. On the destination server, an asynchronous task is immediately started to unpack the rules. This asynchronous task may be scheduled to run before the mailbox-move procedure completes, causing an Event ID 1151 to be logged in the Application log of the Event Viewer. This does not indicate a problem with the mailbox move operation. When the task to unpack the rules completes successfully, Event ID 1154 is logged in the Application log.
