Where is the setting? I want to save emails on my device longer.

In your Message list, press the Menu button, select Options, select General Options. Scroll to the bottom and next to "Keep Messages:", make your setting. Save your changes.

I already had the setting at 3 months, but if I scroll to the bottom it only takes me back to March 27. Where are the rest of the email messages?

Maybe they got deleted. How much free memory do you have?

How do I confirm free memory?

Fill Free reports 5887944 Bytes

Good or bad?

Bad. Recommendations range from 10-14mb free. Follow the Sticky Thread on how to free up memory.

Did some housekeeping, now 10618508 Bytes, better?

Better, but if it drops back down (which it will) you may start to lose e-mails.

Sorry for the ignorance, what/where is a sticky?

Definitely keep an eye on your File Free. It sounds like you dropped to 0 at some point and the BB deleted some email to free up some space.

I think the sticky is at the top of the General subforum.
