  • The Mail Setup dialog shall open up, click on Data Files button.
  • Now you may be confronted to 2 situations:
    • Path to .pst file is already present----> select the mail folder (highlight) and click on "Set as Default".
    • .pst file is absent -----> click on Add -----> browse for mail folder and click on "Set as Default".
  • Close the Mail Setup dialog.


Note that: Prior to these manipulation, make sure that your .pst file is not locked in read only mode.
  • Right-click on the file > Properties > Uncheck "Read-Only" attribute.
