Hi

In my example

1. I query my document library to get the files that I want to attach to the email
2. I then loop through the items collection within the Files object that is returned by the Query a list
3. Query a list does not return the actual file (from what I can see) so I then use the “Get a File by ID” within the loop to retrieve the file.
4. Inside the same loop I then add the file to a collection, which will then be used in the attachments section of the email event.
