Although the Control/Command + Return shortcut is a useful way to quickly send emails from Microsoft Outlook, it can be activated accidentally. For example, you may be using the Control/Command + V shortcut to paste a passage of text and then press return to start a new line before your fingers are fully released, and before you know it your half-finished email has been sent.

Fortunately, there is an easy way to disable this shortcut on both Windows and Mac. Our step-by-step walkthroughs below explain how.

A Quicker Way To Send Emails

Show Mac Walkthrough


  • Click on the Apple symbol in the top left corner of the screen and open System Preferences

  • Select Keyboard, then open the Shortcuts tab from the top of the window

  • From the menu on the left, select App Shortcuts

  • Click on the + icon to add a new shortcut

  • From the Application drop down list, select Microsoft Outlook

  • Assign the Menu Title to ‘Send’ to ensure that the correct function is carried out

  • The Keyboard Shortcut needs to be set to a keyboard combination which is extremely unlikely to be accidentally pressed. A personal favourite is Option + Shift + Command +

  • By pressing Add, this new shortcut will override the default Alt + S and Control + Return keyboard shortcuts.

  • You can test this by attempting to send an email to yourself. Neither of the pre-set shortcuts should send the message, but the newly assigned combination should.



The Alt + S combination should produce the German character ß, with the Command + Return producing a double-spaced line break


Show Windows Walkthrough


  • The first time you press Control + Enter in Outlook for Windows, you will receive a notification asking whether or not you would like to enable this shortcut to send emails. There is also an option to tell Outlook: “Don’t show this message again”. This will save the selected option and the message will not return

  • If this message is not appearing, your account is likely to be already set up with one of these options

  • If you would like to deactivate this keyboard shortcut, or you would like to enable it if it is not currently working, follow the steps below

  • From Microsoft Outlook, click on the File tab in the top left corner, then select Options from the left-side menu

  • From here, open the Mail tab on the left and scroll down to the Send options on the right

  • Locate the ‘Control + Enter sends a message’ section and tick the box. This will show the message when the Control + Enter shortcut is carried out

  • Now you can select your preferences regarding this shortcut. Beware though, that the Alt + S shortcut will still send the message



    A message will not send with no recipients – if you’re worried about sending an email prematurely, leave the Sent field blank until it’s ready to be sent
