Identify deprecated accounts
Security Center recommends: "Deprecated accounts should be removed from your subscriptions."
Improve this recommendation by identifying the "deprecated accounts".

All Security guidance should include a link to a document detailing the criteria and data used to generate the score. This is the only way to map back to the source of the issue and attempt to resolve it or ignore it if we determine we can accept the risk. This should not be hard. Someone had to write the rule to make it show up in security center. Just publish the darn rule.
