Faculty and staff can turn on the AutoComplete list in Outlook.


Outlook maintains the Auto-Complete list. The list is used by both the automatic name-checking feature and the automatic completion feature. The Auto-Complete list, also known as the nickname cache, is generated automatically when you send email messages from Outlook. The list contains SMTP addresses, LegacyExchangeDN entries, and display names for people to whom you have sent mail previously.
The Auto-Complete list for Outlook is specific to Outlook and is not shared by Outlook Web Access (OWA). OWA maintains its own AutoComplete list.
