Well, I did manage to locate a backup file which nicely restored my communications as of a year ago. It was very weird to open my Inbox after swapping the older database into the system, to discover all the conversations I had been having in April 02 staring at me!! The job was different, and a lot of other things as well, and it took a minute to recover my place in the present!!
This means I now have most of your addresses, and I will abide in your first suggestion with divine confidence for any others!
Access isn't in evidence in my system, but this version of MS Offi e does maintain a database -- that's what I had lost.
