The Autocomplete feature is designed to make it easier for users to send emails without having to remember the exact email address of the recipient.

This feature is especially useful for users who frequently send emails to the same group of people or who have a large number of contacts in their address book.

Autocomplete is a built-in feature of Outlook and is enabled by default.

However, there are instances where the Autocomplete feature may not work correctly. In such cases, it is important to troubleshoot the issue to ensure that the feature works as intended.

To ensure that Autocomplete works correctly, it is important to keep your Outlook contacts up-to-date.
