What's new in the Move Mailbox tool

The new or improved functionality of the Move Mailbox tool in Exchange 2003 includes:
  • Mailbox move from Exchange System Manager In Microsoft Exchange 2000 Server, any work with mailbox objects had to be done from the Active Directory Users and Computers console. In Exchange 2003, Exchange Tasks can be run from Exchange System Manager. You can run Exchange Tasks on multiple mailboxes by using either the CTRL key or the SHIFT key to select the mailboxes that you want to move. You can select mailboxes in the right pane of Exchange System Manager when the Mailboxes node is selected in the left pane (under the specific mailbox store).
  • Performance improvements One major improvement in Exchange 2003 is that the Move Mailbox task is now multithreaded. This feature means that you can move multiple mailboxes at the same time. This capability dramatically reduces the time that is required to move multiple mailboxes.
  • Schedule In Exchange 2003, you can schedule mailbox moves to start at a certain time of the day (for example, during hours when users are logged off or the network is not as busy). Additionally, you can set the finish time so that the Move Mailbox task also stops on schedule. For example, you can configure to Exchange 2003 to move x number of mailboxes from 22:00 to 03:00 only.

    If there are mailboxes that are being actively moved when the finish time arrives, all their messages are moved back to the source server, and the mailbox on the destination server is deleted. Essentially, the Move Mailbox operation for those mailboxes is rolled back instead of being completed. Any mailboxes that were moved before the finish time remain moved. Any mailboxes that were not moved before the finish time must be rescheduled and moved manually because the finish time includes time of the day and the date.
  • How corrupted items are handled The Exchange 2003 Move Mailbox tool has built-in functionality to handle possible corrupted items that are found during the mailbox move. The Move Mailbox tool can perform the following actions if corrupted items are found:
    • Create a Failure Report This option notes in the final Move Mailbox report that the mailbox contains corrupted items. The mailbox is not moved.
    • Skip Corrupted Items and Create a Failure Report This option skips any corrupted items that cannot be moved and moves the rest of the items. This option assumes that those corrupted items that cannot be moved will be deleted when this mailbox is moved. You can also define how many corrupted items to skip. For example, if you set this threshold to 5, and the Move Mailbox task encounters four corrupted messages, the mailbox move succeeds. If the Move Mailbox task encounters six corrupted messages, the mailbox move fails, and any messages that have been moved already are moved back to the source server. Additionally, the Move Mailbox tool always notes any problems in the final Move Mailbox report.
  • Reporting After the Move Mailbox task is complete, you can choose to view the detailed log file of the Move Mailbox operation. The logs are saved in XML format to the following path:
    systemdrive\Documents and Settings\profile name\My Documents\Exchange Task Wizard Logs
    The Exchange 2003 SDK has XSL/HTA files that show how the format of XML reports can be changed to a more readable format.

Move Mailbox Q & A

Q1: If the Move Mailbox tool is multithreaded, how many threads can it create at the same time? How many mailboxes can the Mailbox Move tool move at the same time?

A1: By default, the Move Mailbox tool creates four threads. Four mailboxes can be moved at the same time.

Q2: Can the Move Mailbox tool move mailboxes between earlier versions of Exchange, or can it only move mailboxes to or from Exchange 2003?

A2: The Move Mailbox tool can move mailboxes from Microsoft Exchange Server 5.5 (Exchange Server) to Exchange Server 2003, from Exchange Server 2003 to Exchange 2000 Server, and from Exchange 2000 Server to Exchange 2000 Server. However, the new Mailbox Move functionality is only available in Exchange 2003. Therefore, you must initiate the mailbox move from the Exchange 2003 computer.

Note You can also initiate the mailbox move from a computer that has the Exchange 2003 Exchange System Manager installed.

Q3: Can a mailbox move operation still be done from Exchange Tasks in Active Directory Users and Computers ?

A3: Yes, as long as Exchange 2003 Exchange System Manager is installed on the computer where the mailbox move is initiated.

Q4: Can multiple instances of the Move Mailbox task be run at the same time?

A4: Each instance of the Move Mailbox task can run four threads. Depending on your server hardware and load, you may be able to run multiple instances of the Move Mailbox task at the same time. Microsoft recommends that you test this capability on a server-by-server basis.

Note To use Exchange 2003 management tools, the schema must be updated by installing an Exchange 2003 server. Or, if you are using Exchange 2003 ESM or ADUC without having installed an Exchange 2003 server, you need to run Exchange 2003 Setup by using the /forestprep switch. If you do not update the schema, Move Mailbox will not work correctly.
