Internal mail messaging provides the ability for multiple users to view a particular document without making a copy of it, removing it from the system or having to provide the document handle number for clarification. When you attach documents to messages in internal mail, you are really attaching a shortcut to the actual document within OnBase.
Note:
If a user is sent an attachment in internal mail and does not have rights to view the Document Type it belongs to, the user is unable to open the attachment. If the user does not have rights to modify document Keyword Values, the user does not have the ability to Add/Modify Keywords or Re-Index the attached document.
