An outlook 2003 user states that when sending out an email and when they
type in a letter in the "to" area the email addresses that were in memory
when you type a letter or name are gone. They said they didn't do
anything
different. The addresses are in the contact list but there is nothing in
memory so you have to type the whole address in. Is this possible or can
address in memory be deleted or removed?
