Have you ever left your computer on, only realizing later that you wouldn’t be able to get back at it until a few hours? Well, I must admit that I have this foolish habit.
And hence, it became very import for me to find a way to switch off my computer even while I would be away. I did not want to rely on third party software. I decided to use a tool that’s always open on my computer.
We know that Windows uses Shutdown.exe to switch off our computer. We have also learned that MS Outlook can launch applications on receipt of emails and rules verification. Let’s see how we can use this capability of Outlook to trigger a shutdown.
Note: You must have Outlook installed (and up and running) on your computer. It should also be connected to the internet so that the desktop email client is ready to receive emails and trigger the shutdown process.
Step 1: Create a .bat file. First create a text file and then save it as .bat. Remember the save location.
Step 2: Before you close the file, put this in it: %systemroot%\system32\shutdown.exe -s -t 0. Also shown in the image below. Save and close the file.

Step 3: Now open MS Outlook. Under Home tab, go to Rules and expand the menu. Select Manage Rules and Alerts.
Step 4: On the Rules and Alerts window chick on New Rule while under Email Rules tab.
Step 5: Start off by selecting your template as Apply rule on messages I receive. Click on Next.
Step 6: This is the most important step as it determines what rule should be applied. You may have your own conditions but my suggestion would be to have a mix of many to restrict unwanted shutdowns.
Step 6 (a): Select the following rules. For me there is a reason to each:
through the specified account– If you have multiple email id’s configured with MS Outlook you must choose which account the rule applies to.
sent only to me– The motive is to restrict the email rule trigger based on recipient list.
with specific words in the subject– Another constraint so that the receiving email is identified better.
with specific words in the body– Sometimes, only the subject may be ambiguous. So a body makes it more refined.
on this computer only– If you have Outlook configured with same email addresses on multiple machines you must be cautious about the machine you want to apply the rule to.
Step 6 (b): Once you have selected the conditions you need to specify the content by clicking on each of those links in the second half of the window. Here are my samples:-
Step 6 (c): Back on the main window, verify that you have associated all conditions. Then click on Next.
Step 7: Next comes the action to be applied when an email is received and all the conditions match. Select start application and delete it.
The action for start application will do your job. However, if you do not delete it the rule may apply again and again on opening Outlook, resulting in a loop.
Step 7 (a): For starting application action, click on the link and select the file you created at the beginning of the tutorial. Click on Next.
Step 8: I do not think you require any exceptions here. So ignore this window and click on Next.
Step 9: Give the rule a name for future references, turn it on and click on Finish.
Step 10: That’s it. You are done. Now you can turn off you computer remotely.
Triggering Remote Shutdown
When you want to remotely turn off you computer just create a new mail with proper subject and body (as defined in the rule conditions) and send it to the account to which the rule applies. If Outlook is up and running and it receives the mail your computer will be shutdown.
You think you are done? Not yet. With all this effort the computer will be shut down on receipt of a matching email from any email account around the world.
So, go back to Step 6 (a) and select one for the condition from people or specific group. Map it to the account you are going to use to send out emails for such Shutdown trigger.
