Export a mailbox to a PST file using PowerShell

At some point in their life every Exchange admin will need to export a mailbox to a PST file.  In older versions of Exchange this was done using ExMerge but it’s now even easier in Exchange 2010 using the New-MailboxExportRequest PowerShell cmdlet.  Here is an example of how to use it:

New-MailboxExportRequest -Mailbox dave@webbworld.local -FilePath \\WW-EX-01\PSTs\Dave.PST

Note: the FilePath parameter must be specified as a UNC path

The export request will then be placed into a queue and progress can be monitored using the Get-MailboxExportRequestStatistics cmdlet:

Get-MailboxExportRequest | Get-MailboxExportRequestStatistics
