Hope I can explain this so it is understandable.

On a new computer with Vista Home Premium, I had no problem importing my OLE address book from the old machine. In OLE on the older computer, in the address book, I had a folder for SELDOM USED CONTACTS, email address I used once or twice a year. It was a folder that showed in the drop down menu when I composed a new message and clicked the little icon to the left of the address space. Clicking that icon brought up the address book and only the addresses I didn't have in the Seldom Used Folder showed. Since there weren't many of them it was easy to scroll through and pick the ones I wanted.
