About encryption keys
If your BlackBerry® device is associated with an email account that uses a BlackBerry® Enterprise Server or BlackBerry® Desktop Redirector,
your device is designed to use an encryption key to protect data as it travels between the BlackBerry Enterprise Server or BlackBerry Desktop
Redirector and your device.
You should generate a new encryption key every 2 weeks.
Generate an encryption key
To perform this task, your work email account must use a BlackBerry® Enterprise Server that supports this feature. For more information, contact
your administrator.
If your email account uses a BlackBerry Enterprise Server that does not support this feature, you can generate an encryption key using the
BlackBerry® Desktop Software, if it includes the email settings tool. For more information, see the Help in the BlackBerry Desktop Software.
