deleted email appears twice in the trash box

I can see how that would cause some trouble, user_hb9mdk when you need to search through twice the number of emails when making sure you didn't miss anything important. Do you only use the Xfinity inbox for your email or do you use a third party email client as well? I have never heard of this happening before, but it seems like something that could be easily overlooked considering it's already in the trash folder. 

I just use Xfinity - but it's OK. I'll deal with it. Thank you for replying.

Thank you for reaching out to the community about this, @user_hb9mdk. While I haven't heard about this specific peculiarity before, it's possible someone out there will be able to chime in. Right now, all of my messages (the ones that do not go to spam, anyway) are auto-forwarded to my primary email address. I'm wondering if there is a setting that is causing your messages to auto-duplicate the same way when you try to delete them. You might want to try going through your settings to see if anything in there looks out of place.
