Probably not, but it depends on your version, which you did not mention.

Thanks for the advice. Sorry, I use Outlook 2003. I tried the advice in the
tip you sent. I could not get it to work because I had previously changed how
the DL members names were shown. E.g., instead of jsmith@something.net, I
changed it to Joe Smith. When one copies these names, it is as if the "deep"
information is not copied. Thank you again.

The method usually works with Outlook 2003 because it normally includes both
the familiar name and the email address in the Email Display As field. If
you've altered that, then it won't work.
