About message classifications
If your BlackBerry® device 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 email account must use a BlackBerry® Enterprise Server that supports this feature and your
administrator must turn on message classifications.
Your BlackBerry device is designed to use the default message classification when you send a message to a contact that you
have not 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 device tries to use the message classification that was used for the last message.
