Generally when the BB does not show the email it is due to setup.
Add a BlackBerry email account
If you set up a BlackBerry email account (normally in the format user@<serviceprovider>.blackberry.com) on a previous BlackBerry device, to continue to receive messages for that account on your BlackBerry 10 device, you must set up a forwarding email address and then add that email address to your device.1.
On the Add Account screen, tap Email, Calendar and Contacts.2.
Enter the email address.3.
Enter the password for the account.5.
On the Forwarding screen, complete the fields to add a forwarding email address.7.
Tap Next.Note: It can take 5 to 15 minutes before your email is forwarded to the forwarding email address.
To receive your BlackBerry email on your device, make sure that you add the forwarding email account to your device.
