If I understand you correctly, it appears you have
thr "From" column appearing in your Sent Items folder
rather than the "To" column (yes?)...
If so, right-click on the column heading line (the one
that has the titles of each of the columns), then scroll
down the options and pick "Field Chooser". This should
show a small window with all the available fields you can
display in that view - simply "drag" the "From" field off
of the column heading line, then drag the "To" field from
the chooser window into its place. You can add, delete or
re-arrange the various columns by dragging them around
too. Once you close the Field Chooser window, the
settings stay in place and you'll need to repeat the
whole process if you want to make any changes.
Hope this helps...
