  1. Windows PowerShell 3.0 is required.

    If you are on windows 2012 R2 then you are already on windows PowerShell 3.0 but PST capture may not pick it so you need to do the following.

PST Capture Agent – Client side deployment

We have to follow the below mentioned steps to deploy PST Capture agent for the domain

Open GPMC.msc

Click on “Create a GPO in this Domain, and Link it here” and name it PST CapAgent and click ok.

Right click and edit the GPO

Go to the properties and disable computer configuration settings

Expand User configuration and select Scripts (login/logoff) then double click on Logon

Click Add

Browse Script name

Copy both Agent Msi under logon directory.

We will execute the following steps to discover the PST file in the client computer.

Specify locations to search and ignore then click next

You can schedule it for later as well then click next

After this we need to click on Search All Now or we can do one by one. Now we will see PST search is running

Search will finish in sometime and show us the PSTs below as shown in the screenshot below:

Click on PST Search and select “Export PST Search Results”

Give a name and click save.

    I have tried this program earlier when we had Exchange 2010, and that worked great for migrating PST files to users Online Archive.
    However, this does not work on Exchange 2013. Or have you gotten it to work there?

  2. Espen Says:
