Here's the problem: I have 2 computers. When I send a message on one
computer and display it later on the other it has my name in the "to"
column, rather than in the "from" column. The "from" column is blank.

The same thing happens on both computers.

When a message is copied from "sent items" in one hotmail account to another
hotmail account, and then copied or moved back again, the "from" and "to"
columns are then properly displayed.

As a result, under "sent items" I have each sent e-mail saved twice - one of
which displays properly on one computer while the other displays properly on
the other computer.
