Exchange 2007 SP1 introduces the following functionality for exporting mailbox data:

• You can export mailbox data from a mailbox to a .pst file. To export to a .pst file, you must use the PSTFolderPath parameter to specify the path to the .pst file to which data will be exported.
  You can use the Export-Mailbox cmdlet to export data to either a folder or a .pst file. The source and target mailboxes must exist on a server that is running one of the following versions of Microsoft Exchange:
  
  • Exchange Server 2007
    
  • Exchange Server 2003 SP2 or a later version
    
  • Exchange 2000 Server SP3 or a later version
    
  You cannot export data to a .pst file from a mailbox that is in a recovery storage group (RSG).
  
• You can merge the data that you export into an existing target folder by using the AllowMerge parameter.
  
• You can use the Export-Mailbox cmdlet to delete associated messages or to include associated messages in the export process. Associated messages contain hidden data with information about rules, views, and forms.
  
• If you use the DeleteContent parameter and do not specify the TargetMailbox parameter, you can delete content from the source mailbox without exporting it to another mailbox.
  
• You can filter the messages that are exported based on recipients and senders. To filter on recipients, use the RecipientKeywords parameter. To filter on the sender, use the SenderKeywords parameter.
  

By default, the Export-Mailbox cmdlet exports all empty folders, special folders, and subfolders to the target location. To specify folders to either include in or exclude from the export, use the IncludeFolders or ExcludeFolders parameter. The special folders include:

• Inbox
  
• Deleted Items
  
• Drafts
  
• Junk E-Mail
  
• Outbox
  
• Sent Items
  
• Journal
  
• Calendar
  
• Contacts
  
• Notes
  
• Tasks
  

The Export-Mailbox cmdlet exports all message types, including messages, calendar items, contacts, distribution lists, journal entries, tasks, notes, and documents.

The Export-Mailbox cmdlet also exports messages from the dumpster. Messages from the dumpster are converted to regular items in the folder or .pst file to which you export data.

Note:

If you use any keyword parameters, the Export-Mailbox cmdlet will first export all of the messages, including messages in the dumpster, and then search the target mailbox for messages that meet the keyword criteria. Messages that were in the dumpster on the source mailbox are converted to regular messages in the Deleted Items folder on the target mailbox and will also be searched for keywords. The Export-Mailbox cmdlet then deletes messages on the target mailbox that do not match the keyword criteria. If you also use the DeleteContent parameter, Export-Mailbox will then delete the messages that match the keyword criteria from the source mailbox.

For more information about messages in the transport dumpster, see How to Recover a Deleted Item.

The Export-Mailbox cmdlet does not export rules.

You must specify a destination mailbox by using the TargetMailbox parameter. You must also specify a folder on the destination mailbox where you want to export data by using the TargetFolder parameter. The TargetFolder parameter specifies the top-level mailbox folder that will be created on the destination mailbox. This folder will contain a subfolder called Recovered Data - <source mailbox alias> - <date time stamp>. The subfolder contains the exported folders and messages within those folders.

Note:
In Exchange 2007 SP1, if you specify the AllowMerge parameter, the name of the subfolder will not include a date-time stamp.

Note:
In Exchange 2007 SP1, you can specify a path to a .pst file to which data will be exported instead of specifying a target mailbox and target folder.

If the target folder that you specify already exists on the target mailbox, the exported data will be added to the existing folder. If the target folder does not exist, it will be created.

To perform this procedure, the account you use must be delegated the following:

• Exchange Server Administrators role and local Administrators group for the source server and the target server
  
• Full access to the source and target mailboxes
  

For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Permission Considerations.

Also, before you perform this procedure, be aware of the following:

• To grant full access to a mailbox, use the Add-MailboxPermission cmdlet and specify FullAccess for the AccessRights parameter. For example, if Admin01 needs to export data from John's mailbox to a mailbox called Export, you must first run the following commands:
  
  Add-MailboxPermission -Identity john -User Admin01 -AccessRights FullAccess
  Add-MailboxPermission -Identity Export -User Admin01 -AccessRights FullAccess

• To export data from an Exchange 2003 or Exchange 2000 mailbox, the account you use must be delegated the Exchange Administrator role for the administrative group in which the server resides.
  
• To export data from a .pst file, you must run the Export-Mailbox cmdlet from a 32-bit computer that has the following installed:
  
  • The 32-bit version of the Exchange management tools
    
  • Outlook 2003 Service Pack 2 (SP2) or Outlook 2007
    
  For information about Exchange 2007 management tools 32-bit download, see Microsoft Exchange Server 2007 Management Tools (32-Bit).
  
• If you export data to a folder in another mailbox, the target mailbox that you specify must exist before you run the command.
  

Exchange 2007 SP1

 To use the Exchange Management Shell to export mailbox data

• To export the special folders and empty folders of the mailbox user John to a folder called MyData on the mailbox ExportMailbox, run the following command:

  Export-Mailbox -Identity john@contoso.com -TargetMailbox ExportMailbox -TargetFolder MyData

• To export data to a .pst file called john.pst located at C:\PSTFiles, run the following command:

  Export-Mailbox -Identity john@contoso.com -PSTFolderPath C:\PSTFiles\john.pst

• To export data from a group of mailboxes, such as all mailboxes for which the user title begins with "VP," run the following command:

  Get-User | where { $_.Title -ilike "VP*" } | Export-Mailbox -TargetFolder VPData -TargetMailbox ExportMailbox

• To export data that was received between February 2, 2005, and February 15, 2005, to a .pst file, run the following command:

  Export-Mailbox -Id john@contoso.com -StartDate "02/02/05" -EndDate "02/15/05" -PSTFolderPath C:\PSTFiles\john.pst

• To export only data from the Sent Items folder, run the following command:

  Export-Mailbox -Id john -IncludeFolders '\Sent Items' -TargetFolder 'John Sent Items' -TargetMailbox ExportMailbox

• To exclude folders from the export, such as excluding items in the Junk E-Mail and Contacts folders, run the following command:

  Export-Mailbox -TargetMailbox ExportMailbox -TargetFolder MyData -ExcludeFolders "\Junk E-Mail","\Contacts"

• To use filters to specify which items in the source mailbox to include in the export, run the following command:

  Export-Mailbox -Identity contoso\john -TargetMailbox ExportMailbox -TargetFolder MyData -ContentKeywords "merger" -AttachmentFilenames "*orgchart*" -StartDate "03/01/2006 12:01:00" -RecipientKeywords tony@fabrikam.com

  This example exports all items from the mailbox user contoso\john that meet the following criteria:

  • Contain the keyword "merger" in the message body or in the content of an attachment.
    
  • Have an attachment that is named *orgchart*.
    
  • Are dated later than 03/01/2006 at 12:01:00 A.M.
    
  • Have tony@fabrikam.com as one of the recipients.
    

• To find and delete items from a group of mailboxes, such as all mailboxes on a database, run the following command:

  Get-Mailbox -Database DB1 | Export-Mailbox -TargetMailbox ExportMailbox -TargetFolder VirusData -SubjectKeywords "Virus message" -DeleteContent

  This example first gets all the mailboxes on database DB1 and then searches for items that contain the string "Virus message" in the subject line. It will export the items to the mailbox ExportMailbox and will delete those items from the source mailbox.

• To find and delete items from a group of mailboxes, such as all mailboxes on a database, without exporting the items to another mailbox, run the following command:

  Get-Mailbox -Database DB1 | Export-Mailbox -SubjectKeywords "Virus message" -DeleteContent

In Exchange 2003 or Exchange 2000, you can use the Microsoft Exchange Server Mailbox Merge wizard (ExMerge.exe) to export mailbox data. The following table lists scenarios for using ExMerge.exe in Exchange 2003 or Exchange 2000, and the solution for performing this task in Exchange 2007.
