8330 is deleting the e-mails on my handeld after I view them

Question

My BB is deleting my e-mails right after I open, view and close them from my handheld. This has been an ongoing issue I have had with my current and old BB. I opne an e-mail read it and then clise it. When I try to open it back up it is gone.
Why is this? I would like the e-mails that I opend and do not personaly delete to stay on my handeld for at least 7 days.
How do I do this?

Most likely your BlackBerry is running out of onboard memory. When a BlackBerry becomes critically low on memory it will automatically delete email messages, text messages (SMS), and call logs in order to keep a minimum amount of free space available. This functionality is by design.
To free up memory on the BlackBerry, complete as many of the following steps as possible. Some steps may not apply to all devices. Steps may be skipped if desired.
