a few months back, I did the free upgrade to Windows 10 from windows 7. I tried it for three months and decided I did not like it, I thien reinstalled windows 7. Now in setting up my outlook, I notice that my address book and email folders are not coming up in outlook. How can I access them.

I'm guessing you did not revert back to Windows 7 but you did a clean install , correct ?
If that's true , you'll have to set Outlook back up again .
If you reverted back to Windows 7 than it may be in a windows.old file ?

This is a prime example of why we back up everything we can't afford to lose.
I learned that from a friend
