Emails are deleted automatically from Inbox?

Hallo, I have a problem with Yahoo mail. All my messages are automatically directed to trash and I don't have any filter nor POP settings to move all email in other email clients. I use Yahoo mail in WLM, iPhone and iPad. I searched the Help section but the answers provided are not solving my problem. How can I proceed and get in touch directly with the technical support?

I have iphone 5s and all my messages after 2/3 days
are deleting from my ibox?

I solved it for me by tapping: 1. Settings, 2. Accounts & Passwords, 3. Outlook (my mail provider), 4. Mail Days to Sink (at the bottom). I chose 1 Month. It had been set on 1 week before and not only are my emails staying but it actually brought back those that had been deleted prior to this change.

  • Why do my emails delete themselves automatically? Some but not all emails I received are deleted automatically. They are not spam or junk, but they are no where to be found - not in the trash/deleted messages, inbox, junk or spam. I know I received them because they show on the iPhone notification screen, but when I click on them, they are not there at all. Can't find it on computer, yahoo web mail, or iPhone hand set. This has happened since about a week ago. Any idea why and how to fix this?

  • My iphone automatically deleted my conversation? So i had a conversation with my friend that had been going on for months now. I woke up this morning and checked for a message from him and THE ENTIRE CONVO WAS GONE. I don't know what happened. I honestly don't even know if he texted me know because the conversation is gone and i don't know when it was deleted. How could this have happened? Does iphone deleted messages for some reason? Or did i just do it in my sleep or something haha.
