Solution 1Recommended

Enable and Update the Outlook Auto-Complete List

Turn on the Auto-Complete feature in Outlook settings and send an initial email to register the contact's name in the suggestion cache.

Outlook's Auto-Complete list is built from the recipients you have previously emailed from that specific computer. If a contact has not been emailed recently, their name might not appear until you send them a message at least once.

1
Open Mail Options

Launch Microsoft Outlook, click on 'File' in the top left corner, and select 'Options' from the bottom of the menu pane.

2
Navigate to Send Messages

In the Outlook Options dialog box, click on 'Mail' in the left-hand navigation pane, then scroll down until you find the 'Send messages' section.

3
Enable Auto-Complete

Check the box that says 'Use Auto-Complete List to suggest names when typing in the To, Cc, and Bcc lines', then click 'OK' to save your changes.

4
Register the Contact

Compose a new email message, manually select the contact from your Address Book (or type their full email address), and send the message. The next time you type their name, Outlook will suggest them automatically.

Enable and Update the Outlook Auto-Complete List
Local Cache Behavior: The Auto-Complete cache is stored locally on your computer. If you switch to a new PC or use the web version, you may need to rebuild your Auto-Complete list.

Frequently Asked Questions

Why did my Outlook Auto-Complete suddenly stop working?

This usually happens if the Auto-Complete cache gets corrupted, or after migrating to a new computer or updating Microsoft Office. Emptying the Auto-Complete cache in the Mail settings and rebuilding it often resolves the issue.

How do I remove a wrong email address from the Outlook Auto-Complete list?

Start typing the name or email in the 'To' field. When the incorrect suggestion appears in the dropdown list, hover your mouse over it and click the 'X' icon next to the suggestion to permanently delete it from the cache.

Does the Address Book automatically sync with the Auto-Complete list?

No, the Auto-Complete list operates independently of your Address Book. It only stores names and addresses you have previously sent emails to. Simply adding a contact to your Address Book will not make them appear in Auto-Complete until you email them.
