Introduction Why Manually Add to Your Outlook AutoComplete?

The AutoComplete list in Outlook 365 is a time-saving feature, automatically suggesting email addresses as you type. However, it relies on emails sent to populate. This guide provides a workaround to add contacts directly, avoiding the need to send test emails and speeding up your workflow.

This method is particularly useful for adding frequently contacted individuals or groups without cluttering your sent items or waiting for natural email exchanges. This guide is compatible with Outlook 365 and Outlook 2016.

5. Check AutoComplete: Open a new email, and start typing the email addresses you just added; they should now appear as suggestions.

6. Delete the Emails: Delete all the emails from your Outbox folder to prevent them from being sent later.

Important Notes Things to Remember

The Outlook AutoComplete list has a limit, typically 1,000 entries. After reaching this limit, Outlook removes the least-used entries to make room for new ones.

Entries in the suggested lists are not in alphabetical order; Outlook arranges them by usage frequency, putting the least-used at the bottom. Keep this in mind when searching for less frequently used addresses.
