Best Practices

Optimize PST Archiving

You can optimize the archiving process by following the set of steps described under the following sections:

Prevent Creation and Modification of PSTs

Detach PSTs

Prevent Creation and Modification of PSTs

Enabling Group Policy setting on the Active Directory to:

  • Disable creation of new .pst files
  • Disable opening of new .pst files
  • Disable adding content to current .pst files

Outlook 2010 is used in this example.

  1. By default, there are no Microsoft Office templates in the Group Policy Administrative Templates. Click here to download Office 2010 Administrative Template files.

    After you download the files, extract and keep them in a folder.

  2. Create a folder called PolicyDefinitions and add the template to the Group Policy by moving the downloaded template in this newly created folder:


  3. To copy the language files according to your requirements, create a folder named EN-US under PolicyDefinitions and copy the contents of en-us from ADMX folder to the newly created EN-US folder.

    %systemroot%\sysvol\domain\policies\PolicyDefinitions\[MUIculture] (for example, the U.S. English ADMX language-specific file will be stored in %systemroot%\sysvol\domain\policies\PolicyDefinitions\en-us)

  4. To open Group Policy, log on to a Domain Controller > Run > Administrative Tools > Group Policy Management.
  5. In the Group Policy Management Editor, expand Administrative Templates: Policy definition > Microsoft Outlook 2010 > Miscellaneous > PST Settings.
  6. In the right pane, select Prevent Users from adding .psts to Outlook profiles and/or prevent using Sharing-Exclusive .psts.
  7. In the Prevent Users from adding .psts to Outlook profiles and/or prevent using Sharing-Exclusive .psts dialog box, select Enabled.
  8. Under the Options list, select No .pst can be added.

    By default, the policy will be effective based on Group Policy interval settings.

  9. To enforce the policy immediately at the command prompt type:

    C:\Users\u1\gpupdate /force

Detach the PSTs

Run a logon script called hound.vbs on the required computers to:

  • Remove .pst from the default Microsoft Outlook Profile
  • Restart Microsoft Outlook

Navigate to the software_installation_directory\Base\hound.vbs. The logon script collection approach uses the Windows logon routine to process .pst detachment.

Use a Group Policy object to deploy the logon script.

  1. Log on to a domain computer with Domain Administrator privilege and start the Group Policy editor for the appropriate Organizational Unit.
  2. Expand User Configuration > Windows Settings > Scripts (Logon/Logoff) and double-click to open Logon.
  3. Click Show Files and copy Hound.vbs into this location.
  4. Click Add to open the Edit Script window.
  5. Enter cscript.exe for the Script Name field.
  6. Enter hound.vbs /D.

    Note: This works only if the default Microsoft Outlook profile is configured.

  7. Click OK and to save the changes and close the Group Policy window.
