Click Outlook Data File (.pst)> Next.

Select the name of the email account to export, as shown in the picture below. Only information for one account can be exported at a time.

Make sure that the Include subfolders check box is selected. This ensures that everything in the account will be exported: Calendar, Contacts, and Inbox. Choose Next.

Choose the email account you want to export.

Click Browse to select where to save the Outlook Data File (.pst). Enter a file name, and choose OK to continue.

Note: If you’ve used export before, the previous folder location and file name appear. Type a different file name before choosing OK.

If you are exporting to an existing Outlook Data File (.pst), under Options, specify what to do when exporting items that already exist in the file.

Choose Finish.

Outlook begins the export immediately unless a new Outlook Data File (.pst) is created or a password-protected file is used.
