Have you gone back to the last e-mail and clicked on mark unopened? Sometimes if you do that and then re-open it will go away. It's annoying isn't it? And welcome to crackberry!
There's another fix for this rather than resetting. This applies to SMS as well as E-Mail.
Go to the inbox. Press "T" to get to the top of the list - it should highlight the current date (or whenever you last received a message). Press the Menu key and select "Mark Prior Opened." Even if there are no unread messages, it should clear the notification. I've done this in the past with success. I think 4.5 fixes the problem all together.
i had the same issue a while back, i wanted to try and get cleared without a batt pull so i just sent myself a text and deleted it and the notification went along with it. Batt pulls do fix most issues though.
I had this happen to me recently, and a simple batt pull solved it. Have you checked all of your folders? Maybe a missed call situation?
^^ Fixed it for me earlier.
Also make sure its an email and not a missed phone call or something like that. Check "Messages". I wondered the same thing when I first had a storm a while back ago.
I had a notification that would not go away no matter what i tried (battery pull, delete prior, save sms, save email, etc.) Eventually, i had to send myself an email for the newest email to show up. Weird..
I found that having my SMS and my Inbox separate seems to have caused the problem. Once I found the SMS message I'd apparently missed and read it, my message count went back to zero. Combine SMS and your inbox and you will always see both e-mail and SMS.
Okay none of them was working for me but then i went onto the main menu, press the menu button the show all, a globe thing should come up or maybe something else thats hidden, Good luck
alright, i came across this thread and instead of starting a new one i thought i might aswel bring this one back......
basically i have the email icon at the top of of my phone
i have tried
battery pulls
sending an email to myself
going in my saved messages folder
deleting my call record.
Mark Prior Opened worked for me. Deleting one saved message that I did not know I had did not work, nor did removing the battery. I hope that you guys who are not fixed find a fix because it is REALLY annoying.
