6. Import and Export Mailboxes
You
can import and export mailbox data to or from other Exchange mailboxes
or PST files. There may be circumstances where you want to import data
stored in existing PST files into Exchange mailboxes, such as if you are
migrating users from using PST files to using Exchange 2010 archive
mailboxes. Exporting mailbox data also allows you to perform the
following tasks:
Create a point-in-time snapshot of a mailbox
You may need to create regular snapshots of specific mailboxes without
needing to retain an extended backup set of all mailboxes on a mailbox
databases.
Meeting compliance requirements You may need to export the contents of specific mailboxes when meeting legal discovery requests.
Remove specific messages from multiple mailboxes You can use the export mailbox process to remove sensitive messages that were inadvertently sent to multiple mailboxes.
A default import or
export targets all folders, including empty folders, special folders,
and subfolders. To restrict which folders are imported or exported, use
the IncludeFolders or ExcludeFolders parameters when using Import-Mailbox or Export-Mailbox.
Mailbox import and export have the following limitations:
It is possible to export only one mailbox at a time, though mailboxes can be exported sequentially.
When you use Export-Mailbox, both the source mailbox and the destination mailbox are in the same Active Directory forest.
Importing
and exporting data requires a 64-bit computer that has both Exchange
Server 2010 management tools installed and the 64-bit Microsoft Outlook
2010 client installed.
Import-Mailbox cannot be used to import data to a mailbox hosted on previous versions of Exchange Server.
It is not possible to import mailbox or PST data to a public folder or a public folder database.
You can perform a selective
export using the RecipientKeywords, SenderKeywords, SubjectKeyworks,
StartDate, and EndDate parameters. When you use the Export-Mailbox
cmdlet with the DeleteContent parameter but do not specify a target
mailbox, you are able to delete specific messages in targeted mailboxes.
This allows you to selectively delete messages across a number of
targeted mailboxes. For example, if you wanted to remove a message that
was sent to a large number of users who had mailboxes hosted on mailbox
database MBX-DB-ONE called “Christmas Party Photos,” which was sent by
Kim Akers, you could use the following command:
Get-Mailbox -Database MBX-DB-ONE | Export-Mailbox -SubjectKeyWorks "Christmas Party
Photos" -SenderKeyWorks "Kim Akers" -DeleteContent

7. Archive Mailboxes
Archive mailboxes are a
feature new to Exchange Server 2010. Personal archives eliminate the
need for PST files for Outlook 2010 by allowing users to store messages
in an archive mailbox that is accessible to Outlook 2010 and OWA. This
simplifies the process of legal discovery and the enforcement of message
retention policies, which can be difficult to apply when messages are
stored locally on users’ workstations rather than on Exchange mailbox
servers. Archive mailboxes are available only with Exchange Enterprise
edition CALs.
You can create an
archive mailbox when you create a primary user mailbox. It is also
possible to create or remove an archive mailbox when a user has an
existing mailbox. Archive mailboxes are stored in the same mailbox
database as the user’s mailbox. When you move a user’s mailbox to
another server, the archive mailbox is automatically moved to the
destination mailbox database as well.
You can enable an archive on
an existing mailbox by selecting the mailbox in the Recipient
Configuration\Mailbox node of EMC and then clicking on the Enable
Archive item in the Actions pane. You can use the Enable-Mailbox
command with the Archive parameter to enable an archive mailbox for an
existing mailbox. For example, to enable an archive mailbox for Rich
Haddock’s mailbox, issue the following EMS command:
Enable-Mailbox "Rich Haddock" -Archive
To disable an archive
mailbox, select the mailbox under the Recipient Configuration\Mailbox
node and then click Disable Archive in the Actions pane. You can also
use the Disable-Mailbox
cmdlet to disable an archive mailbox. For example, to disable the
archive mailbox associated with Rich Haddock’s mailbox, issue the
following EMS command:
Disable-Mailbox "Rich Haddock" -Archive
In the event that you
accidentally disable the archive mailbox for a user and you want to
reconnect it and the disabled archive mailboxes is still retained in the
mailbox database because of retention policies, you can reconnect it
using the EMC by viewing the Disconnected Mailbox node under Recipient
Configuration in EMC.
