A reminder is a notification in Outlook that shows a short message that allows you to act on an email.

Outlook templates are pre-designed or customized formats that are used for regular emails, but the only problem is you need to attach the files (if needed), manually.

  • Click the OK button to complete, from now onwards Outlook reminds you automatically if you may forget attachments.

You can uncheck the feature permanently, but in case you need to send the current email without an attachment and the reminder is active for further emails, you need to click ‘Send Anyway’ from the popup reminder that appears as we mentioned at the start of the previous section.

This warning message can help you to avoid forgetting attachments in an email message. The forgotten attachment detector can go off right after you hit Send, which can help you to remember attachments in the future.


In conclusion, Outlook Attachment Reminder is a useful addition to Outlook. It offers great reminders and is easy to set up. It really will help some busy people, and you could find value in the tool.
