Explanation

To enable IM and Presence high availability, two prerequisites must be met: (1) A secondary server (IMPSub) must be added to the Presence Redundancy Group as the secondary presence server - without this, the system has no failover target. (2) The 'Enable High Availability' checkbox must be selected and saved on the Presence Redundancy Group Configuration page - this is the explicit toggle that activates HA. The error message 'High availability is not enabled' directly indicates that option E is missing. Without a secondary server configured (option D), HA cannot function even if enabled. Restarting the Cisco Presence Engine or modifying DNS records alone does not resolve this configuration-level issue.
