Some (not all) emails disappearing / deleting themselves from folders in the Mail app on iPhone 4S

Try this: Open your email on your iphone. go to Mailboxes, then under Accounts, click on your gmail or yahoo or whatever your email acount is. Click on All Mail. Emails which you put in folders on your Mac will appear under All Mail. You can even search for emails that are stored on the server.

Hope that helps!

In my case it's a Yahoo problem. They sent an email a few weeks ago saying they found an issue. They created a 'synch ' folder that contained all my missing messages. Only took them over 8 months to admit and resolve.

Thank you! After applying your information to my iphone, my emails returned. Thank you again...very helpful.

I had this same problem too only on my Hotmail/Live email accounts. Gmail seems fine. I don't have Yahoo mail synced in my iPhone. The "in days sync" only appears on Live/Hotmail accounts.

Settings > Mail, Contacts, Calendars > Select your Live/Hotmail account > Scroll Down > Mail Days to Sync > Select your preference

Hello,

To begin, I do realize that this thread is over a year old, and I apologize if this is bothersome but I just found some new info that might help those of you who are still concerned that Apple Mail might be deleting your important emails for no reason. Well, I too have been having this problem with random emails being deleted from my iPhone 4S up until today. I discovered that the problem itself lies within your computer (hopefully you use a Mac like me 😁). There is a setting in the advanced section of the Mail preferences that controls how often the mail servers will delete/keep copies of already opened emails. Here is how to fix it so that no email ever gets deleted again:

1) Go to Mail Preferences (command-comma)

2) Go to Accounts > Advanced

3) UNCHECK the section that says "Remove copy from server after retreiving a message"

4) Close the window, but SAVE (if you don't save, it won't apply)

Hopefully now the emails that you receive on your phones will never be deleted unless you want them to.

Have a great day.

Had iPad 2 with iOS 5 - no problem at all for years in a row. Never lost an email.

Just bought iPad 3 with iOS 6 - drafts / outbox disappear with no reason.

I was typing emails from an airplane and hitting send (disconected). When connected, I expected to have my e-mails sent, but they was just vanished. No one received it and they are not on my iPad or Gmail server.

By the way, if you try to add a Exchange Gmail account, apparently it is not supported by Google anymore.

Several business emails was lost and never reached detination until I noticed the problem.

IPAD BECAME UNTRUSTABLE FOR WORK!

This problem is really severe and should be THE most important fix ever.

Can I trust anything else on my iPad? Notes? Photos? Apps?
