DL and Milly:
Thank you to both of you for your prompt responses.
DL's observation that my "...HD has insufficient free space for the
correction operation of the o/s..." was RIGHT ON THE MONEY.
After transferring sufficient data from my HD to "storage" - I opened up 34
GB of 142 Total (this took close to 4 hours!).
Then I ran scanpst.exe, which took another hour.
It repaired the Outlook.pst.
I thank "backed up" the 3.9 GB Outlook.pst.
Finally, I opened Outlook and archived what I though was at 2/3's of my 3.9
******Why do 3.0 GB still "show" in my Outlook.pst - AFTER the archiving?
Those emails and attachments are no longer in my OUTLOOK INBOX/SEND BOX.
******Is there a "compaction" program that must be run?
Thank you again. I look forward to you answers on the aftermath questions.
