imported two e mail address from talk talk but did not change them from pop 3 to I Map is there any way to edit them as i want to keep both address the same

or can I delete them and then re import using different settings?

Have asked for help in Sheffield Meadowhall store they said talktalk will not support I Map but have checked they say they do

Ah well so much for Apple experts :-(
