I opened Address Book within Entourage and found all entries assigned ³None² as a category. Over 500 entries had previously been set to one of fifty categories [one for each company]. Since I am contracted by many companies, I don¹t know who works for which company if the categories are gone as I didn¹t enter company information-only emails for the most part. Notwithstanding the current issue, how can I set the computer so that when it syncs with iPhone after updates, this doesn¹t happen. [Last week, an update for iPhone was available and I downloaded it]. Theresa
