In an exchange of emails with a friend, one of her responses to me went into my Spam folder. This was one message out of a thread of messages back and forth. I found it and clicked Not Spam.
The message in question then reappeared in its proper place within the thread. But when I responded and hit Send, her message that had been previously misidentified as Spam disappeared again from the thread. Attachments to one of my previous messages to her also disappeared.
I looked in my Spam folder and in my Trash folder. I did a search through all folders. It's nowhere to be found. Her disappeared message also had attachments that I would like to have.
Is there any way to recover it? It's scary that one message and those attachments can be just wiped out of a thread like that.
