• Customer Community
  • Create Case Form component (not the newer Contact Support component)
  • Napili template
  • Authenticated customer community users only - no guest users
  • Community Users have profile P with read - create - edit on Cases
  • Attachments enabled on Create Case Form component
  • Observed starting Winter 19
  • No triggers on Attachment SObject


  • Authenticated community user clicks button that displays Create Case Form and completes form
  • Clicks on Add Attachment, selects file
  • Then clicks Submit button to submit the case w/ attachment


  • Case submitted but error in red box appears: Your case was submitted, but the attachment wasn't saved. Please create a new comment and attach the file to it.

So, how do I enable attachments to successfully upload?

Turns out that you need to enable a checkbox associated with attachments on Accounts and Contacts:

Setup | Communities Settings |Community Role and User Settings

"Lets customer users access notes and attachments" -- check true

enter image description here

This box had been unchecked for the org prior to Winter 19 yet evidence existed community users were able to upload attachments to Cases prior to Winter 19.
