It’s very easy to write an email that is supposed to include a document or spreadsheet, then get to the end of the message and forget to include that file.
Usually, you might just send an embarrassing follow-up email with the attached file, but Outlook 2013 has something that you can use which reduces the likelihood of this happening.
Our tutorial below will show you how to enable the attachment reminder in Outlook 2013 so that the email program gives you a little wanting if it thinks you forgot to attach a file.
How to Turn on the Microsoft Outlook Attachment Reminder
- Open Outlook.
- Choose the File tab.
- Click the Options button.
- Select the Mail tab.
- Check the Warn me when I send a message that might be missing an attachment box.
- Click OK.
Our guide continues below with additional information on how to enable the attachment reminder in Outlook 2013, including pictures of these steps.
The ability to include attachments with emails makes it much easier to share pictures, documents, or other types of files with your contacts.
But as you are typing the body of an email that will eventually contain an attachment, it can be easy to become distracted and forget to actually include the attachment. I know I have been guilty of this, and I’m sure that many others have as well.
Outlook 2013 contains a feature where it will display a pop-up window if it thinks that you have forgotten to include an attachment with your email message.
This typically occurs when it notices that you have used the word “attach” in your email.
However, the attachment reminder is a setting that can be turned off, so follow our guide below to see how you can turn it on in your copy of Outlook 2013, or even check to ensure that it is already enabled.
