How to backup email by creating a new PST on Outlook 2010

Step: 1

At the top left of your Outlook ribbon,

choose File > Options > Advanced > Export

Step: 2

Select Export to a file and click Next

Click the Outlook Data File (.pst) and then click Next.

Step: 3

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 way everything in the account will be exported: Calendars, Contacts, and Inbox.). Click next.

Click the Browse to select where you want to save the Outlook Data File (.pst). Type in a file name and click OK. 

Once done, click Finish

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

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

If you’re creating an Outlook Data file (.pst), an optional password can help protect the file. When the Create Outlook Data File dialog box appears, type the password in the Password and Verify Password boxes, and then click OK. In the Outlook Data File Password dialog box, type in the password, and then click OK.

• If you’re exporting to an existing Outlook Data File (.pst) that is password protected, in the Outlook Data File Password dialog box, type the password, and then click OK.
