Change the default signing and encryption option
Your BlackBerry smartphone is designed to use the default signing and encryption option when you send a message to a
contact that you haven't previously sent a message to or received a message from. Otherwise, your smartphone uses the
message history to suggest a signing and encryption option.
You can set your smartphone to try to use the default signing and encryption option for your outgoing messages instead.
However, if message classifications are turned on, the default signing and encryption option might not be able to be used
depending on the security requirements of a message's classification. For example, if your default signing and encryption
option is set to Sign and you compose a reply to a message that is classified as confidential, the signing and encryption option is
set to Sign and Encrypt instead of the default signing and encryption option.
1. On the home screen or in a folder, click the Options icon.
2. Click Device > Advanced System Settings > Default Services.
3. Change the Default Encoding field.
• To try to use the default signing and encryption option for outgoing messages, set the Outgoing Message Encoding
Suggestion field to Use Default Encoding.
• To use the signing and encryption option based on the message history, set the Outgoing Message Encoding
Suggestion field to Use Message History.
4. Press the
key > Save.

About message classifications
If your BlackBerry smartphone is associated with an email account that uses a BlackBerry Enterprise Server that supports this
feature and your administrator turns on message classifications, the BlackBerry Enterprise Server applies a minimum set of
security actions to each message that you compose, forward, or reply to, based on the classification that you assign to the
message. Your administrator specifies the message classifications that you can use.
If you receive a message that uses message classifications, you can view the abbreviation for the classification in the subject
line of the message and the full description for the classification in the body of the message. You can also view the abbreviation
and full description for the classification for a sent message in the Sent Items folder.
Change the default message classification
To perform this task, your work email account must use a BlackBerry Enterprise Server that supports this feature and your
administrator must turn on message classifications.
Your BlackBerry smartphone is designed to use the default message classification when you send a message to a contact that
you haven't sent a message to or received a message from previously. If you have sent a message to or received a message
from the contact previously, your smartphone tries to use the message classification that was used for the last message.
1. On the home screen or in a folder, click the Options icon.
2. Click Device > Advanced System Settings > Default Services.
3. Change the Default Classification field.
