Exchange 2010 SP3 - Import PST to respective Mailboxes

Posted on 2014-12-09
Last Modified: 2015-11-13
I have exported Mailbox to PSTs with respect to the Username, i.e. John Smith - JSmith.pst.  No we have a new Exchange server 2010 with SP3 installed.  

My questions are:

1. What would be the appropriate command to import the PST in to the user's mailbox


2.  Is there a Exchange Management Shell Script that I can use to take all the PSTs and import them in to the respective mailbox?

My Boss has me under a TIGHT deadline so any assistance would be greatly appreciated.

Great article explaining all the steps to do this can be found on  
In essence you make sure all your .pst files are named using the mail account name of the user, i.e Paul.Daniels.pst for Paul daniels (Or whatever naming scheme you use pdaniels.pst etc)
Then off you go, powershell will import them all for you :D

Dir \\2010ad02\PST-Files\*.pst | %{
    New-MailboxImportRequest –Name ImportOfPst –BatchName ImportPstFiles –Mailbox $_.BaseName –FilePath $_.FullName

Open in new window

Heres the full article

For some reason, with SP3, I have to initita tte the request first:


Prompts for PST location

Then asks for alias

Afterwards, it queues the export.

Thanks for the lead Neilsr

Neilsir, is there any way to tell if the imports are running?  I ran, Get-MailboxImportRequest | Get-MailboxImportRequestStatistics and it shows nothing in queue.  I right-click and run with Powershell, a window popped up and then closed.  I ran it directly from Powershell and it just went back to the Powershell prompt.
