To save some copying steps, here is one way:
Copy the entire list into an address field of a blank Outlook mailnote (the To, or CC or even the BCC field.
At that time (depending how your Outlook is set up), or after you close and save the otherwise blank mailnote - in which case you will need to re-open the otherwise blank mailnote) you will see all the properly formatted email name (where there is a 3part "firstname.lastname@example.org") you will see those email names now underlined.
Then just select each individual email name and do a right-click, and select [Add to Outlook Contacts].
That will open one Contact entry form, with the email name entered in the correct field. You can add additional detail, if you want. Then just save and close.
Repeat the right-click for each underlined email name.
Does anyone know how I could detach a distribution list that someone forwarded to me in Outlook (Office 2003 SR-1 Pro)to my own Contacts folder without having to copy each name individually?
