With the DE 7.1.x releases, MA 5.0 will be supported only with legacy features because these versions cannot exploit the new features introduced in MA 5.0. To review the MA 5.0/ePO 5.1.1 feature dependencies, see KB71298.
Hope this answers your questions
Just spent a few hours working this issue with support. The tech consulted with Tier 2 & 3, my issue they confirmed is a known issue that will be fixed in agent 5.0.3. They could not give me a time frame for agent 5.0.3 and a POC was not available.
The tech thought the issue was related to legacy features but in my case it is not the issue as the EEADMIN_1000 policy does not show up even after these features are disabled, This makes Drive Encryption not function as the policies won't enforce. For now we shall avoid Agent 220.127.116.11 for any encrypted systems.
