Phantom unread emails: Mail shows 5 unread messages, but there are none...

I've got four email accounts set up with my iPhone 4 (updated to latest software). Yesterday, however, one of those inboxes started showing that there was one unread email on the account (an imap account), but when I go to view the message list there are no unread emails there. And this morning, it started showing five unread messages, but again no unread messages were there.

The 'unread messages' don't show up in Mail on my iMac either (and the Mail icon in the doc does not show any phantom 'unread' messages).


Has anyone else encountered this problem, and if so, how was it solved?

20" iMac 2.0GHz Intel Core Duo, original iPhone, iPhone 4, Mac OS X (10.6.4), 4GB RAM, 250GB HD, 128MB VRAM

I get this issue every single day, and it is specifically reproducible. Here is the scenario:

1) I have two mail accounts configured on my iPhone, one is my work account and is disabled on the phone, the other is my gmail account which is always enabled on my phone

2) Each morning, when I head into work I enabled my work email account so I can start reading my work emails for the day. This downloads all the new messages from the server and displays them as unread.

3) I read some of them, but not all of them.

4) Once I get to my office, I read all of the rest of my new work emails from the Mail app on my MacBook Pro.
EXPECTED: The messages that are read on the mail app are updated as read messages
OBSERVED: On my iphone, not all of the messages have their statuses changed to read. Some of them always remain as unread messages

5) Next, I delete some of the messages read from my computer from the email server altogether.
EXPECTED: These messages would also appear deleted when using the mail app on my iPhone
OBSERVED: Not only are the messages not deleted, but they are still listed as unread

The only way to resolve this each day is for me to select each message and view it for a second to have the unread message indicator removed. I have to turn off the mail account and turn it back on for it to correctly sync with the mail server and correct the mistakes.

There is clearly a problem within the iPhone mail app with retrieving updates from the mail servers.

I have an iPhone 4 running iOS 4.2.1 that I purchased in November. Before that, I had an iPhone 3G S and never experienced the issue on my 3G S. My MacBook Pro was used with both devices.

I had the account showing one email unread when in fact there were no emails in my inbox, or in fact anywhere else. I had cleared them all out, including the deleted items and sent items: there were really zero messages left in my account, but according to my iPhone 4, of the zero messages, one was still unread!.


We conclude therefore, that it is an unresolved bug. I did go into settings and turned mail on and off and reset the phone and that did clear it, so there is a workaround for the iPhone 4 at least.

HI guys haven't read all 200 posts but what worked for me was to go to mail account and reduce number of days to sync email in my case no limit down to 1 day dropped back into email and refreshed phantom disappeared then reset back to no limit.

SImple and fast and problem has not reappeared.

thanks for all the advice above and hope this adds and helps some

I found a more appropriate solution..

Go to your inbox and try to search for emails by pulling the email inbox screen down


On the search field instead of giving an real word to look up for, simply start typing "unread" and it will autosugest to show all unread emails. Click on that and you'll get those phantom unread emails on your screen. Mark them as read and that's it!

Please go through my solution.. It's not hard to do this every time it happens:


Go to your inbox and try to search for emails by pulling the email inbox screen down


On the search field instead of giving an real word to look up for, simply start typing "unread" and it will auto suggest to show all unread emails. Click on that and you'll get those phantom unread emails on your screen. Mark them as read and that's it!
