Frequently Asked Question

Outlook is still showing Addresses. Why?
Last Updated 2 years ago

Outlook builds your suggestions as you go - which means a lot of us will have addresses appear when we start typing a name. While these addresses will work for now, when the addresses stop working around September or October, these will no longer deliver. It's a good practice to clear these when you see them now.


To Clear one at a time:

  • Start typing a name
  • Hover the name that pops up as a suggestion
  • Click the X at the right

How to clear the whole AutoComplete list

Method 1

  1. Open Outlook.
  2. On the File tab, click Options.
  3. Click the Mail tab.
