There are two different ways that you can delete the saved/cached versions of email addresses. It is possible to delete these entries individually or delete the whole repository. You may have to do the below if:

• you have updated a contacts email address in your contacts
• a UniSA staff member has had a change in name
  NOTE: By default an alias is added to staff accounts, so in this instance your email will still reach its destination, but their display name will be the old name
• you regularly email someone, but have not added them to your contacts 

Delete Individually

1. In a new email start typing the address you wish to delete
2. Outlook will pre-empt options underneath.
3. Hover mouse over desired address and click delete option to the right
