what is the "On My Computer" account in Entourage? can i get rid of it? the account i use is using Exchange and appears as a separate account in the side bar menu. can someone explain the difference between my email account and the "On My Computer"? specifically, when i try to make a group with my contacts that are located within my Exchange account, it places the group in the address book under "On My Computer" and i can not get it into the contact list where i draw the contacts from.
