How to Delete Cached Email Address in OWA

If you have an old/outdated email address that keeps showing up in your autocomplete list inside of Outlook Web Access that you would like to remove. 
1. Click the New button to open a new message.
2. Type the first three character of the cached name into the To field to trigger the AutoComplete feature.
3. Press the Down Arrow key on your keyboard to highlight the name or email address you wanted to delete.
4. Press Delete on your keyboard to remove it, (on Mac Laptop you will need to press FN + Delete.)
Note:  If you are on a Mac laptop you may need to connect an external keyboard for this to work!  The laptop keyboard does not have a true "delete" button but can be fooled by using the FN + Delete combination.
