We just recently switched to Lightning and I am running into an issue with emailing off of an Opportunity. One of our reps sent an email with several attachments and can't seem to view the attachments on the email message (Task).  When I look at the message, I see that it has the name of the file listed as an attachment but there is no actual attachment. I also found that I can search for that file name and pull it up in files but it is not attached to a record.  I am confused as to why I cannot access it directly through the email message (Task).  Does anyone know why I wouldn't see the attachment?  Is there a setting I need to enable?
