For individual one-to-one message threads, go to the mobile app, select the one-to-one conversation (from Contacts or Recent) and then click the “Burn” icon. Either party to a one-to-one message thread via the app can burn the one-to-one message thread.

For group message threads, log into the Command Center, go to “Messages”, select the group, and then click the “Burn” icon. Group messages can only be burned by the account Administrator or assigned Operators.
