How to Back Up Outlook Emails?

When you are using email for work, there are major chances that you are using an Exchange or IMAP account. Exchange and IMAP servers automatically archive Outlook emails so that you can access them anytime or anywhere.

If you have an Exchange account, check your admin on how to access archived emails. To back up the message folders locally, you can automatically move/delete older items with AutoArchive or export items to a .pst file that you can restore later as needed and use by importing.

  1. Select File > Open & Export.
  2. Now select Import/Export.
  3. Select Export to a file.
  4. Now click Next.
  5. Select Outlook Data File (.pst). Then, select Next.
  6. Select the mail folder to back up and select Next.
  7. Choose a location and name for your backup file. Then click on Finish.
  8. To ensure no one has access to your files, enter and confirm a password, and then select OK.

You can forward, reply, or search through the stored messages in a .pst file as you do with other messages.
