Managed Mail Replica policy checking

[dpastov]

For managed mail replicas it's not at a straightforward check of a setting, we need to check:

1. Whether there is an organizational policy or > 1 organizational policy
2. Whether there are exception policies that may exclude users from these
3. Then whether the referenced active desktop settings include mail settings for managed replicas:

To me I think there are maybe three levels:

1. One organizational policy that has MMRs on its desktop settings doc and no exception policies: full success 2a. An organizational policy with desktop settings with MMRs but there are multiple organizational policies or exception policies exist: partial success 2b. At least one explicit policy exists with desktop settings with MMRs: partial success
2. No policies with desktop settings or those desktop settings do not have MMRs specified: fail
