Solution 1Recommended

Remove an Autocomplete Entry in Outlook Desktop

This is the quickest and most effective way to remove a wrong email suggestion directly from your computer using the Outlook application.

Outlook stores recent email addresses in a separate autocomplete cache. Because it is independent of your address book, you must manually delete the cached entry directly from the composition window.

Open a New Email

Launch Microsoft Outlook on your computer and click on the 'New Email' button to open a new message composition window.

Trigger the Autocomplete Suggestion

Start typing the incorrect email address or the recipient's name in the 'To' field until the suggestion dropdown appears.

Delete the Suggestion

Hover your mouse over the incorrect email address in the suggestion list and click the 'X' icon next to it. Alternatively, use the Down Arrow key to highlight it and press the Delete key on your keyboard.

Frequently Asked Questions

Why does a deleted contact still show up in Outlook autocomplete?

Outlook maintains a separate local cache for autocomplete suggestions that is independent of your main Address Book. Deleting a contact from your address book does not automatically clear their entry from this cached autocomplete list.

Can I clear the entire autocomplete list at once in Outlook?

Yes. In Outlook Desktop, you can clear the entire list by navigating to File > Options > Mail. Scroll down to the 'Send messages' section and click the 'Empty Auto-Complete List' button.

How do I stop Outlook from automatically suggesting email addresses?

To disable the feature completely, go to File > Options > Mail in Outlook. Locate the 'Send messages' section and uncheck the box that says 'Use Auto-Complete List to suggest names when typing in the To, Cc, and Bcc lines'.

Will removing an autocomplete entry delete my past emails with that person?

No. Removing an address from the autocomplete suggestion list only deletes the typing shortcut used when composing new messages. Your previous emails and inbox history with that address will remain completely intact.
