How to Upload Files to Box with Email

You can easily upload files or send attachments to a specific Box folder by email when you enable the Allow uploads to this folder via email option. You can then forward email attachments or send files to the email address generated for that folder to upload your files. If you decide to forward email attachments to the folder, only the attachments will be uploaded, not the content of the message.

Please note the following:

  • Enabling this feature will allow anyone with the email address to upload to the folder. Not all email providers support encrypted transmission, which can pose a security risk when uploading sensitive content. Take this into consideration when enabling this feature on a particular folder.
  • Upload via email only works for file attachments, the body of the email will not be uploaded to Box.
  • The cumulative size of the attachments cannot exceed 80MB.
  • The folder owner and sender will receive a notification that files were uploaded successfully.
  • Collaborators will also receive a notification if upload notifications are enabled for the folder.
