Canvas: Canvas Strips Attached Files from Email (Known Issue)

Task: This article describes situations in which Canvas may remove attached files from emails between Canvas and external email sites



Canvas allows you to receive message notifications through preferred email/SMS addresses. Users can reply to these notifications directly through those preferred addresses, but any files attached to that reply from the email or SMS platform will be stripped out and not seen in Canvas by the recipient.

For example, you use your USNH email account to reply to a Canvas email from your instructor.  You attach a file to that email, but your instructor will not receive it and you will not get any notification that the attachment was not sent. This ability to respond to emails outside of Canvas is an extremely useful tool for written communication, but not for file transfers.

Affected Platform

  • Canvas email replies through any email system.

Resolution or Work-around

  • If you need to include a file attachment in a Canvas conversation/Inbox message make sure that you submit the message and attach the file from the Inbox tool in Canvas instead of your email/SMS client outside of Canvas.
  • Let the receiver of the email to view the email and the attachment through the Canvas Inbox.


This will explain what situations in which Canvas may remove attached files from emails between Canvas and external email sites
