That is not how my Junk E-mail works and I don't know why it works the way
it works. In other words, when I go to the Junk E-mail folder, I can open
the messages for viewing. I need to be careful to not click the
"Not Junk" button while viewing the message unless I want to see the next
message in the folder, since when the message is moved to the inbox, the
message after it in the Junk E-mail folder is opened.
By design, emails in the Junk E-mail folder can't be opened or viewed.
If you want to see the contents of a Junk E-mail message, click the
"Not Junk" button. It will be moved to the Inbox, where you can view it.
