How do I open my MS Outlook archive file(*.pst)?

If your MS Outlook archive file isn’t already shown in your Outlook email navigation pane, you can gain access to it by following these steps:

  1. Click File | Open | Outlook Data File.
  2. In the Open Outlook Data File window, navigate to where your archive file is (i.e. h: space or another network drive).
  3. Select the *.pst file and click OK.

By default your email archive is located in your H: space.  Many LSE students and staff find themselves short of space here.  Now that all LSE email accounts have been migrated to Office365, and contain a 50GB mailbox, you may wish to free space in your H: space by importing your archived emails back into your Mailbox. If you need help with this process, please see our guide on Adding Archived email back to your Mailbox.
