The anatomy of a signature policy - conditions

The conditions tab is used to set criteria which determine the circumstances under which a signature policy is applied to messages:

Once a condition is selected, any options for that condition are displayed as hyperlinks in the lower pane - select these links to refine the condition. Each time a selection is made, any related options are displayed as hyperlinks in the lower pane - select these links to set / refine criteria for the associated condition.

At least one condition must be set for signature policies. If a condition is not selected, the default condition of all Office 365 users is used. Please see the conditions - options summary page for a summary of available conditions.
