  6. Click Browse to select where to save the PST file. Enter a file name, and choose OK to continue. Otherwise, you can choose to leave it at the default.
    1. If you are exporting to an existing PST file, under Options, specify what to do when exporting items that already exist in the file.
  7. Choose Finish.
  8. Outlook begins the export immediately unless a new PST file is created or a password-protected file is used.
    1. If you’re creating an PST file, an optional password can help protect the file. When the Create Outlook Data File dialog box appears, enter the password in the Password and Verify Password boxes, and choose OK. In the Outlook Data File Password dialog box, enter the password, and choose OK.
    2. If you’re exporting to an existing PST file that is password protected, in the Outlook Data File Password dialog box, enter the password, then choose OK.

What data is exported?

    • message rules
    • blocked senders lists
