XADM: Possible Loss of Mail with Move Mailbox

ID: Q168188

The information in this article applies to:

Microsoft Exchange Server, versions 4.0, 5.0

SYMPTOMS

The Move Mailbox command does not move mail from a renamed server-based folder (that is, Inbox) to the new server, if a new folder with the previous name of the renamed server-based folder (that is, Inbox) has been created.

STATUS

MORE INFORMATION

Steps to Reproduce the Problem

Rename any of the four default folders (Deleted Items, Inbox, Outbox, Sent Items). (For example, rename Inbox to Old Inbox.)

Create a new folder in the Mailbox folder with the same name as the original folder (for example, Inbox).

Place some mail in each of the two folders (for example, 3 in the renamed folder and 2 in the new folder).

Log off of the client.

Move the mailbox to another server within the site.

Expected Results

Both renamed folder (Old Inbox) and newly created folder (Inbox) should show up in the mailbox on the new server.

Actual Results

The new mailbox has a folder called Inbox, but no folder called Old Inbox. Messages that were previously in Old Inbox (the renamed server-based folder) will not be found in the new mailbox. Messages that were in the newly created folder "Inbox" on the old server will be in the server-based Inbox on the new server.

Properties of the private info store on the original server no longer show the user that was moved. Properties of Priv IS on the new server show the mailbox and its resources minus the number of messages that were in the renamed folder. (For example, previously Old Inbox had three messages and Inbox had two messages; after the move, Inbox will have two messages and Old Inbox is not found on the new server. If Mailbox Resources had 51 items before the move, it will have 48 after the move.)

This results in mail loss and the administrator must restore from the backup to retrieve the messages for that user.
