REF: E14 Mailbox Role – Move Requests – Part 4

1. New-MoveRequest 會存在AD & target DB’s system mailbox
2. Offline Move 是讓user 無法存取, Online Move 則於搬完後才lock source mailbox
3. MRS Instance check 每個DB’s system mailbox 是否有move request
4. MRS 應該只負責所屬AD site 的move request
5.

New-MoveRequest -Identity Ayla@contoso.com -TargetDatabase "DB02"





1. 
   

   The cmdlet updates active directory and then places a special message to the system mailbox within that Active directory site that a move request has been initiated and the move is set to a status of Queued. Information about the move request is stored in two places: the target database's system mailbox and in Active Directory.
   If the move is an offline move, the mailbox is locked and can't be accessed until the move is in Completed status. For more information about scenarios in which offline moves are created, see Moving Mailboxes Between Exchange 2010 and Previous Versions of Exchange section previously in this topic.

   
   
2. 
   

   All instances of MRS periodically check the system mailbox on every database in its Active Directory site to see if there are any queued move requests. The MRS instance on CAS01 finds Ayla's mailbox in the Queued status.

   
   
3. 
   

   The New-MoveRequest cmdlet will choose an instance of MRS and ask it to process the move request immediately. If the selected instance of MRS is available, it will pick up the move immediately. If not, the mailbox will wait in the queued status until an MRS instance finds the move request.

   
   
4. 
   

   MRS begins to move the data from DB01 to DB02. MRS updates the mailbox's status in the system mailbox to InProgress.

   
   
5. 
   

   When the move is almost finished, Ayla's mailbox will be locked for a short time while the final mailbox synchronization is completed. The status of the mailbox changes to CompletionInProgress.

   
   
6. 
   

   When the move is completed, Ayla's new mailbox on DB02 is activated and the old mailbox on DB01 is deleted. The move request status changes to Completed. Ayla can now access her mailbox after she logs off and logs back on.

   
   
7. 
   

   The administrator clears the move request information from Active Directory and on the system mailbox on DB02 by running theRemove-MoveRequest command, either in the Shell or in the EMC. Until the move request information is cleared, you can't move the mailbox again.

   
   

   A record of the move is kept in Ayla's mailbox and can be accessed by running the Get-MailboxStatistics cmdlet with theIncludeMoveReport parameter.
