Date order

[KARL]

At work I have on my computer (the master which others have access to by necessity) a folder in Outlook Express which contains the record of files I have circultated to a list of recipients - all as SENT messages. While I was away others have somehow deleted four of these which I have recovered through one of the original recipients. However, now the copies of the transmissions of course appear in the date order when I retrieved them, not the date order by when I sent them. The result is that anyone quickly looking for them where they should be will assume they are missing without searching further down the list. Is there a way to get them to where they belong ?
