Changing how names are displayed in already sent and received messages

[Alan]

In Outlook 2003, as a result of the somewhat undisciplined use of the
autoresolve and autocomplete functions and some direct entry of email
addresses, I have emails to and from the same person that display in
separate sections when my inbox or sent mail box is arranged by To or
From. That's because in some cases I used the name as recorded in my
Contacts, in some cases Outlook inserted the name with quote marks via
autocomplete, and in some cases it's just a (e-mail address removed)
address.

I've now turned off Autocomplete so all names will conform to my
Contacts. Is there a way to change stored messages so that all
messages to (for example) the same person will display showing teh
same form of that person's name?

Thanks!
Alan
