How to Turn Off AutoComplete in Outlook 2013

For those on a quick clock: To turn off AutoComplete in Outlook 2013, simply head to the File tab, click Options, select the Mail tab, find the ‘Send messages’ section, and uncheck the box for Auto-Complete suggestions. Then hit ‘OK’. And just like that, no more unsolicited suggestions!

The AutoComplete list in Microsoft Outlook 2013 is something that builds up over time as you write and respond to emails. When a name or email address is added to the AutoComplete list, you can start typing that name or address into the To, CC, or BCC field in a message window, and Outlook will offer some suggestions.

This feature can be useful in a number of situations, but you might find that you prefer not to use it. If that is the case, then you can follow the steps below in order to turn off this functionality.

Looking for More?

Ever found yourself typing an email address in Outlook, and before you can even finish, it suggests the whole thing for you? That’s the work of AutoComplete. While it’s super helpful for many, sometimes it can be a tad annoying. Especially when it suggests an email address you’d rather forget. (Ex-boyfriend’s email, anyone?) So, if you’re looking to turn off this feature in Outlook 2013, you’re in the right place. Buckle up!

Let’s Turn That AutoComplete Off!

Imagine AutoComplete as that friend who finishes your sentences. Fun at times, but not always. Here’s how to (politely) ask it to stop:

  1. Open Outlook 2013. Start by firing up the software. Pretty straightforward, right?
  2. Navigate to the File tab. This one’s at the top-left corner. It’s like the gateway to many magical settings in Outlook.
  3. Options, Here We Come. Once you’re in the File tab, look for ‘Options’ and click on it. This will open a window with all the customization settings you need.
  4. Click on the Mail Tab. It’s like opening the door to all things email-related in Outlook.
  5. Scroll to Send Messages. Here’s where things get a bit more specific. Under the Mail tab, there’s a section titled ‘Send messages’. That’s where you want to be.
  6. Uncheck the Box. You’ll spot an option that says “Use Auto-Complete List to suggest names when typing in the To, Cc, and Bcc lines.” There’s a box next to it. Simply uncheck it.
  7. Apply and Close. Click ‘OK’ to save the changes. Voila! You’ve now successfully turned off AutoComplete.

Remember, turning off AutoComplete doesn’t delete the list of email addresses it has saved. It just stops suggesting them. Think of it as putting that overly-helpful friend on mute.

    Absolutely! Just follow the same steps and check the box instead of unchecking it.

    Nope! It just stops suggesting them. They’re still there, silently waiting.
  • I have another version of Outlook. Will this guide still work?
    This guide is specifically for Outlook 2013. Other versions might have slightly different steps.

A Deeper Dive into AutoComplete:

AutoComplete is like your digital memory jogger. It saves the email addresses of people you’ve previously emailed. While it’s a time saver, sometimes the list can get cluttered with one-time or incorrect addresses.

A Heads Up for Privacy Buffs:

If you’re sharing your computer, be cautious! AutoComplete might suggest personal or confidential email addresses to someone else using your Outlook. Always good to know when sharing is caring, and when it’s not!

Turning off features or customizing them to your preference is all about making technology work for you. And remember, just like a bike’s gears or a TV’s volume, you’re always in control. Happy emailing!
