I feel like a newb every time I post here. I've had my 8310 for a month now and I'm experiencing some issues, and I call them issues 'cause I don't know how to asses them.
Recently I've noticed that my emails are deleting them selves on there own and I don't know how to fix this. I don't have that many emails on my inbox, I usually delete on a daily basis.
Does anyone know what could be happening here and how to fix this.
When the device memory gets below 10 000 000 it will start deleting email & text messages to get the available memory left. You need to remove anything that you are not going to be using. Check the memory in Options > Status
This link will walk you though the process to remove the unnecessary:
If you have your email set up in outlook, and outlook is not set to leave a copy of messages on the server, that could also cause email's to disappear off your phone.
FYI, this was also happening to my girlfriend's curve and I had her do a hard reset and that resolved the issue as well. So while it may have been a memory issue in this instance that's not always the case.
