Exporting and Importing Mailbox Content in Outlook on Windows

About Importing and Exporting
You can export your email and mail folders, calendar and appointments, tasks, notes and additional content from Outlook as a .pst file and import everything in one go onto a different computer or into another mail profile. The .pst file can be saved to other media just like any other file, however it can only be opened within Outlook; other programs will not be able to open a .pst file.
IMPORTANT: if the .pst contains any sensitive or confidential information (i.e. in your messages, attachments, etc.), it must be adequately protected as per data storage and encryption related requirements.

This tutorial covers exporting and importing an entire Mailbox using Outlook versions 2016 or 2013, with notes on any different steps needed if using Outlook 2010.
A Mailbox typically includes your Inbox, Sent Items, Deleted and other mail folders, Calendar, or other items that are listed as sub folders of the Mailbox as it appears in the left Navigation pane in Outlook.
Storing older items via an export or using auto archiving are ways to move messages and other data that you don't access frequently, and will prevent quota issues with items stored on the CUMC email (Exchange) server.

  1. To reach Outlook's Import and Export wizard:
    • Outlook 2016 and 2013: with Outlook open, select the FILE tab in the upper left, then the Open & Export link in the left, then Import/Export.

    In both fields type in a password that will be required when the Personal Folders File is opened. IMPORTANT: If you forget the password there is no way to retrieve it or otherwise open the .pst you are creating; be sure to keep track of any password used here. Select OK to continue.
  8. Your computer will pause as the .pst file is created; if you have a lot of items to back up you may see a window that shows the status of each item as it is backed up. No notice will appear to indicate that the back up is done, simply verify that the "backup.pst" file appears in your Documents\Outlook Files folder when Outlook has finished (if you have changed the location and/or name in step 6 above, look for the appropriate file name/location).
Adding and Importing Mailbox content from .pst file

NOTE: Importing a .pst file allows you to merge items into one Mailbox/list of folders. If you would simply like to open the .pst file and be able to view email messages, calendar items, etc. from within Outlook as a separate list of folders, use the instructions immediately below. To import (merge) items into your existing account folders, click here.
  1. Outlook 2016 or 2013: select the File tab in the upper left corner of Outlook, then the Open & Export link and the option to Open Outlook Data File.
