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.

Well, without doing anything, other than leaving my iPhone turned on in the Email application with the unread mailboxes active the phone eventually found all of the so called "unread" messages, some going back a long, long time and ones that I do recall either reading or deleting as they arrived on my phone.

All I had to do then was go back to the resective mailboxes and select them alll & mark them as read and now I have no "unread" messages on my phone ( I left this for about an hour, in which time I got a few emails that increased the unread number but cleared as normal once I'd opened them )


There's obviously a glitch in the software somewher that's causing this but mine has rectified itself 🙂

Try this it worked for my Comcast POP account and might work for your situation. I went into my email setting on IOS7, selected the account I was having problems with, went into advanced setting and under deleted messages selected the "NEVER" option (i belive the default is "after one week". After doing this I found a bunch of undread messages suddenly appearing on my phone. I then used the new feature in IOS 7 to mark them all as read. (while viewing your inbox - select the EDIT link top right, after select the MARK ALL link bottom left, and then the Mark All as READ feature. This was my final fix - GOOD LUCK!!!

G-mail user:

Fixed my issue, but I only had 1 phantom unread mail.


I was having no luck with the select all -> unread -> read method. But when I turned the device off, (iPhone 5 latest rev.) to clear the RAM and cache, I repeated the method. Went into the mail app and retried it.


A mail from a few days ago popped up as unread. So it fixed itself. I'm OCD about notification badges on my screen, it gives me anxiety when I see one. So even if I don't read the mail thoroughly, I still like to mark it as read.


Hope this might help some.

Sorry...not really tech savy instructions.

so, after pressing 'edit' the 'mark all as read' option should display. press that, then delete, and, 'done'.

for some reason this doulbled the number of 'pantom' emails on my phone (a 5) but repeating the whole process erased them all. make sense?



The 'Search 'unread' suggestion is probably easier in hindsight.

Ok I just finally figured this out on my iphone5s I went into ALL INBOXES and went to EDIT then I hit mark all UNREAD then I went back into Edit and marked all READ. I had to scroll down a bit to a few emails that had multiple extensions (All grouped together ) and manually edit a few but that finally fixed it for me after such a long time of being very frustrated. Hope this helps you!
