If you are uploading Email messages keep the following things in mind:
- Attachments in the Email message are not readable through the document viewer. In case Guests have no download permission on the Email message, upload the attachments separately.
- If an email message is modified, print the email message to a PDF file first and upload the PDF file instead of the email message.
There are edge cases where modified the source file of a modified email message has flaws in the lay out. This may cause a difference in the layout between the supporting program on your PC and the layout in the document viewer. Be advised to check how the email messages show in the document viewer before inviting users.
