Sometimes I hit CTRL+ENTER or ALT+S by mistake and off goes the message as it is Outlook's shorcut for the Send button.
Is there any way I can prevent this from happening?
I think most people can relate with you; getting tangled up in pressing Enter to start a new line and hitting CTRL instead of SHIFT when trying to capitalize your new line or pressing ALT+S instead of CTRL+S to save your draft.
You can prevent this from happening by not addressing the mail yet although this might not be practical, especially when replying to an e-mail. Luckily Outlook allows you to configure what happens when using CTRL+ENTER but to disable the ALT+S keyboard shortcut, you’ll have to edit the Registry.
The first time you use CTRL+ENTER, you’ll be prompted by a dialog asking how Outlook should respond to the usage of CTRL+ENTER in the future. There are 3 states possible;
- Outlook should always send the message (select the box and press Yes).
- Outlook should never send the message (select the box and press No).
- Outlook should always ask you what to do (do not select the box and choose Yes or No).
Not 2 but 3 choices are available here.
When you’ve chosen for state 1 and want to change it to state 2 or have chosen for state 2 and want to change it to state 1, then you can change the following option;
- Outlook 2007
Tools-> Options…-> button E-mail Options…-> button Advanced E-mail Options…-> option: Press CTRL+ENTER to send messages
- Outlook 2010 / 2013 / 2016 / 2019 / Microsoft 365
File-> Options-> section Mail-> option group: Send Messages-> option: CTRL + ENTER sends a message
When you’ve chosen for state 1 or 2 and want to change it to state 3, then you’ll have to delete the CtrlEnterSends registry value name or set its value to 2;
0 = Outlook will not send when pressing CTRL+ENTER
1 = Outlook will send when pressing CTRL+ENTER
2 = Outlook will prompt you when pressing CTRL+ENTER
When this key is missing, Outlook will behave as if its value was set to
To disable the ALT+S keyboard shortcut as well, you’ll have to add the following Registry key;
Note 1: The value name (
AltS) is actually irrelevant for this particular key but it is good practice to use meaningful names.
If you are not very into editing the Registry, then there are also 5 other options to prevent you messages from being sent directly after pressing send.
