Have you ever forgotten to add an attachment to an email although you mentioned that there would be an attachment in the email? It might lead to an embarrassing situation with business partners but also additional and delayed work. The reason for this is simple: you may eventually receive an email from the recipient asking about the whereabouts of the attachment. You then need to write a second email with the files attached which delays your work if you have been waiting for a response and probably also the work of your contact in the process.

Outlook Attachment Reminder is a software addin for the email client Microsoft Outlook which acts as a reminder. The addin will automatically scan the text in the email client for words like attachment or attached.

If those words are found in the email the addin will check for attachments and notify the user if none was found so that the attachment can be added before sending the email.

The Microsoft Outlook addin comes with the option to add words to the addin which will be used to check if the email should contain attachments. You can add words using the options window that the add-in makes available after installation.

You can also add filters that warn you if attachments cross a specified size threshold. The default threshold is set to 10 Megabytes which you can change in the options as well. It enables you furthermore to restrict attaching attachments, or to restrict attachments by file type so that files are blocked from being sent if their file extension is on the black list.

Note that the Outlook Attachment Reminder Suite is compatible with all recent versions of Microsoft's Outlook email program including the recently released 2013 version that shipped together with Office.
