Open Address Book > click the button.

that did not help What button?? left side or right side.?? initially I pressed the button on the right side and it did nothing. Okay its the right side/ but doesn't always work. I had mailing lists and TB deleted them

I've finally after two hours of trying , got it to work Don't know why it has to be this difficult. WEnt to help file and that was totally useless as it was posted in 2015

had to get into the forum to find out how to do it.....2 hours duration!!! .
