Here's a first. Had to import emails from a saved pst file. No problem with the actual import process but somehow it resulted in adding approximately 270,000 blank emails. Yes 270,000. Deleting works but for only a few at a time. Selecting "All" will take forever. I checked the pst file with a pst viewer and none of the blank messages appear. I assume re-importing the pst file in question or any pst file will not delete the blanks.

Any ideas?
