My sent folder is not showing all the emails I have sent. Why is this happening?

This seems to be random, with some showing and others not. Since Thursday, nothing I've sent out is in the sent folder. More worrying, on my iPhone, the entire sent folder has been emptied.

The default setting for sent emails is to save a copy in the Sent folder. Do you know if your account was hacked and your account settings changed?

Why am I not receiving messages on my mobile device?

Why can I see my saved emails under folders on my laptop but not on my cell phone?

  • Why is all of my new e-mail going into my notes folder instead of my inbox? When I check my inbox on my iphone or from the computer, there are not any new messages. When I go into my e-mail account in yahoo mail, my new e-mails are in my notes folder instead of my inbox. On my iphone, there's not a "notes folder" avaliable for me to view. I did not even realize there was a notes folder until I accessed my yahoo mail through the computer. This is the first time I have had this to happen.

  • Why aren't my emails being sent?

I can't from my iPhone or even my laptop& pc. what's wrong with it? how do I get my emails to send. * I use hotmail to send emails. It's my main account. sorry if it's the wrong category, its the closest.
  • Why are my emails from my iphone being sent as attachments? I call up a contact and select the email address. I type the email and send it. But when it arrives to the person I'm sending it to it is an attachment. When it arrives to the recipient it says my telephone number and YOU HAVE BEEN SENT A PICTURE MESSAGE. How can I make my emails be just that an email and not an attachment.
