Autocomplete Email Addresses in Outlook
Introduction
The AutoComplete list is an Outlook feature that displays suggestions for names and email addresses as you begin to type them. These suggestions are possible matches from a list of names and email addresses from the email messages that you have sent.
These addresses are NOT backed up so if you change computers, or upon migrating your mailbox to Exchange Online, you will no longer have access to these addresses.
We recommend that you review your AutoComplete list and create Outlook contacts for anyone that you regularly correspond with so that you always have their information to hand.
