MS Exchange how to export / import mailboxes to PST Print

Exporting and Importing PST Files via Exchange Management Shell

The following steps explain how to export and import .PST files using the Exchange Management Shell (EMS). These operations are asynchronous and may take some time to complete.

Export a Mailbox to PST

1. Grant export permissions

Before starting, assign the required role to the user:

New-ManagementRoleAssignment –Role "Mailbox Import Export" –User acs-hosting\Admin

Important: Restart EMS to apply the new permissions.

2. Start the export process

New-MailboxExportRequest -Mailbox mailboxname -FilePath \\ex2010\export\filename.pst

This command initiates an asynchronous export process.

3. Check export status

Get-MailboxExportRequest

Filter for completed requests:

Get-MailboxExportRequest | Where {$_.Status -eq "Completed"}

4. Remove completed export requests

Remove-MailboxExportRequest

Remove all completed requests:

Get-MailboxExportRequest | Where {$_.Status -eq "Completed"} | Remove-MailboxExportRequest

Import a PST File into Exchange

1. Start the import process

New-MailboxImportRequest -FilePath \\HOSTNAME\sharename\file.pst -Mailbox mailboxname

2. Monitor import status

Get-MailboxImportRequest

View completed imports:

Get-MailboxImportRequest | Where {$_.Status -eq "Completed"}

3. Remove import requests

Remove completed requests:

Get-MailboxImportRequest | Where {$_.Status -eq "Completed"} | Remove-MailboxImportRequest

Remove failed requests:

Get-MailboxImportRequest | Where {$_.Status -eq "Failed"} | Remove-MailboxImportRequest

4. Generate report for completed imports

Get-MailboxImportRequest -Status Completed | Get-MailboxImportRequestStatistics -IncludeReport | Format-List > c:\AllImportReports.txt

5. Bulk import from folder

Dir DC2APST_To_Import*.pst | %{
  New-MailboxImportRequest -Name RecoveredPST -BatchName Recovered -Mailbox $_.BaseName -FilePath $_.FullName -TargetRootFolder Imported_Mail
}

Note

To allow up to 200 corrupt items during import, use:

New-MailboxImportRequest -FilePath \\server\share\file.pst -Mailbox mailboxname -BadItemLimit 200 -AcceptLargeDataLoss
