Exchange 2010 SP1 has a new command to import and export to a PST.
First you need to give yourself permissions to do this with the following command:
New-ManagementRoleAssignment –Role “Mailbox Import Export” –User “<username>”
You will need to close down and open up the console again to gain access to the commands below.
Then you need to run the following to actually Export for a PST
New-MailboxExportRequest -Mailbox user@domain.com -FilePath \\path\to\file.pst
If it's a backup of the archive you're after add -IsArchive on the end
You can check on the progress of the backup with:
Get-MailboxExportRequest
or
Get-MailboxExportRequestStatistics username\MailboxExport -IncludeReport | fl | Out-File c:\temp\output.txt
For full details.
You can clear any old Mailbox requests with:
Remove-MailboxExportRequest -Identity "username\MailboxExport"
or
Get-MailboxExportRequest | Remove-MailboxExportRequest
to remove them all (and be prompted)
Very simple!
