How to clear Microsoft Outlook's Cached Contacts

Microsoft Outlook's AutoComplete feature, is used to learn, and save, emails for you. This results in users not needing to retype, or remember, emails.

If issues arise with AutoComplete not populating (AutoComplete may be full) or there are emails that are no longer needed, you can proactively remove AutoComplete list entries you no longer need.

To clear AutoComplete, see Clear Current Cache, below. In an instance where you would like to delete contacts individually, see Remove Outlook Contacts Individually, below.
