You must first enable probe participation before you can add email addresses for use in the Symantec Probe Network. When you enable probe participation, a Probe account policy group is automatically created and added to your list of policy groups. If you already have a policy group named Probe account, when you enable probe participation, your existing Probe account policy group is renamed to Backup of Probe account <n>. (When Symantec Messaging Gateway must rename more than one existing Probe account policy group, it uses sequential numbers <n> in the group name.)

When you disable probe participation, the Probe account policy group is automatically deleted.
