Sent Items and regular e-mails have been disappearing from the Classic Blackberry device, what can I do?

Emails disappearing from BlackBerry device

It this all emails? Or just older ones.

If older ones, go to Settings > Accounts > select the account > Advanced. Scroll down, tap Sync Timeframe and increase how long messages are retained.

Same here. Today's email are lost.
