I had the E73. The samw probleme happened. The fiest time a restart was enought. But the seconde even a reswt would not do he trick.

I have had the same problem with my Nokia E72.

Just move your messages away from your inbox folder. You can copy them to a new folder if you want, or you can just delete them.

Then restart the phone, and your problem will be fixed.
