• If you use message classifications, verify that the message classification supports the signing or encryption options that you want. Try

using a different message classification.

I cannot open an attachment in an encrypted message

The attachment information might not be available on the BlackBerry® Enterprise Server, your administrator might have set options to prevent
you from opening attachments in encrypted messages, or you might have received the message from an email account that does not support
attachments in encrypted messages.

You cannot open an attachment in a PGP® protected message that was encrypted using the OpenPGP format by an IBM® Lotus Notes® client
working with PGP® Desktop Professional or that was encrypted by the PGP® Universal Server.

Message troubleshooting

I cannot send messages

Try performing the following actions:

• Verify that your BlackBerry® device is connected to the wireless network. If you are not in a wireless coverage area, your device should

send messages when you return to a wireless coverage area.

• If the menu item for sending a message does not appear, verify that you have added an email address, a PIN, or a phone number for

your contact.

• If you created an email address or added an existing email address to your device using the email setup screen in the setup wizard,

verify that you have received an activation message on your device from the BlackBerry® Internet Service. If you have not received an
activation message (the message might take a short period of time to arrive), in the setup wizard, open the email setup screen to send
a service book to your device.

• If you have not received a registration message from the wireless network, register your device. On the Home screen, click the

Options icon. Click Advanced Options. Click Host Routing Table. Press the Menu key. Click Register Now.

• Generate an encryption key.
• Verify that data service is turned on.
• Resend the message.
