SYMPTOMS
When the Exchange 2000 GroupWise Migration Wizard tries to migrate a mailbox, the GroupWise application programming interface (API) that Novell provides may return an error when the GroupWise API gains access to a message attachment in that mailbox. The GroupWise Migration Wizard may log the following event ID 4089 error message:

Event ID: 4089

Source: MSExchangeMig

Type: Error

Category: None

Description: An error occurred accessing an attachment to a message with subject &quot; &quot; in folder &quot; &quot; for user &quot; &quot;. This attachment will not be migrated.



CAUSE
This issue may occur for two reasons:
 * The GroupWise API call to retrieve the attachment returned an error.
 * The GroupWise API call to retrieve the attachment returned the same pointer for the attachment as for the attachment's parent.

In both cases, the attachment is not available. The GroupWise Migration Wizard logs the error message, and then migrates the portion of the message that is available.

The message and its attachments may be available to the GroupWise client, but inaccessible to the GroupWise API. This issue may occur if two or more embedded messages contain attachments. This issue does not affect all embedded message with attachments.



WORKAROUND
To work around this issue, fix the GroupWise mailbox:
 * Move the mailbox to another GroupWise post office. This move may rewrite the attachment to a new attachment table and allow the GroupWise Migration Wizard to migrate the attachment. -or-


 * Manually save the attachment that generates the error to a location outside the GroupWise mailbox.
