Outlook 2013 Tip: Never Forget to Send Attachments

While sending a lot of emails on a busy day, have you ever sent a message saying you attached a file but forgot to include it? Outlook 2013 includes a handy feature that reminds you if it appears you forgot to attach a file.

Outlook 2013 Attachment Reminder

The setting should be enabled by default, but if not, go to File > Options > Mail then under the Send Messages section, verify that “Warn Me When I Send a Message that May be Missing an Attachment” is checked.

Warn of Missing Attachment

Here’s the typical scenario: You compose and email letting the recipient know you’ve attached a file, but forget to actually include it and hit Send.


Outlook will give you an Attachment Reminder message. Click Don’t Send, attach the file, and send the message.

Attachment Reminder

Outlook 2013 looks for a sequence of words in the body and subject of the email. Words that will trigger the reminder would be obvious ones like “attach” and “attachment”. Or phrases like “print attachments”, “enclosed”, “see the attached spreadsheet”…etc. It might not always work (depending on the sequence of words), but it’s good to know this feature will have your back. Especially if you’re sending something to your boss and don’t want to be embarrassed by forgetting it.

If you use Microsoft’s revamped webmail service, it also has an Attachment Reminder you can enable.

    At last! I suggested this to MS two decades ago.

          Really? What’s your primary email client now? Let me guess… Web browser?

            Now that I’m no longer “corporate” I don’t need such a monster, albeit powerful, mail app, so I went to Outlook Express.

    We are all on Win 7 and Office 2013 and this feature will not work. We’ve even tried deliberately sending emails with just “attached, attachment…” etc to try and provoke it!

      Hi Paul – And even after following this guide and rebooting, you’re having the issue on multiple systems?

  5. Richard Holmes May 1, 2014 at 12:05 pm #

    If you are using Outlook as your mail app, it should work.

    Is there any way to add more words that will trigger the reminder?
