My iPhone deletes my yahoo email on its own! (Disappearing emails)

+1

me too. Yahoo! emails just disappear unexpectedly, fun, fun, fun!

(the only emails that seem to be intact are the ones in the sent folder, although with the Yahoo! "sending" problem, it's not like something in the sent folder means it was sent anyway)

I have been experiencing this problem in spades - disappearing Yahoo email, disappeared meaning not moved to trash or any other folder, no trace. I've seen email disappear before my eyes while looking at the header in the inbox hitting no key whatsoever on the iPhone and not even reading the email yet. And I've seen email disappear a day later having read it once. I have not experienced this behavior with my IMAP private server work mail account which I access as much. Most recently I have noticed email disappearing from folders OTHER than the INBOX!! I'd hoped by quickly moving mail to folders I'd make it secure from deletion. But NO!!!

I once asked YAHOO to restore my email from backup to recover an email. I asked for the state the previous day per the instructions. Their response was they could not accomplish this - no further explanation.

Hmm. Had to create a new account to post but it is dunco again here.

I called apple phone support. The tech representative called another tech person. I updated to the latest iphone version 1.1.1=>1.1.2, deleted the yahoo mail account and recreated it. I also set my purge limit 25=>200. Of course, no trouble testing viewing an email at yahoo - the trouble is intermittent so I didn't expect to see a failure. I was advised to watch for a week and to try a reset (home plus power button until grey apple ignore power-off slider) before calling again. The next suggested step is a full restore. My guess is there is some bug shared between apple and yahoo because the mails disappear BOTH places. Yahoo needs to figure out how a mail can disappear. Their mail file system must be getting trashed.

I have the same experience using my local isp and pop. ...it happens two ways;
1. When I read one then the rest disappear
2. Never have deleted email in the trash folder

I can go back to my lap top and get it tho...

I run my own XServe and have experienced this issue with IMAP and the iPhone. I was extremely fortunate to have the since to run a POP backup from a work computer that is always on for all of my critical business accounts, so I was able to go and retrieve deleted emails.

However, this issue is truly disturbing, I can not believe that Apple has not addressed such a serious issue that has been known for apparently over 6 months now.

The issues I have experienced:
- email being deleted entirely from the server after being read from the iPhone
- the entire inbox being deleted of all messages after being accessed from the iPhone

_*Apple, it is not a problem with Yahoo!, considering your own, default, implementation of IMAP via OSX Server 10.4.11 experiences the same issues. It is a problem with the email application on the iPhone, and it's interface with IMAP. Please address this immediately, as currently any email access via the iPhone is unreliable at best and cannot be used for anything other than novelty.*_
