The general steps are as follows:
(box 1, box 2) Create a distribution group that will be used for the root organization (top-level tier). If

desired, you can use an existing organizational unit in your Exchange forest for the distribution group.
Create distribution groups for the child tiers and designate them as members of the HAB. (box 3)

Modify the SeniorityIndex parameter of these groups so they're listed in the proper hierarchical order within the root organization.
Add organization members. Modify the SeniorityIndex parameter of the members so they're listed in the

proper hierarchical order within the child tiers.
For accessibility purposes, you can use the PhoneticDisplayName parameter, which specifies a

phonetic pronunciation of the DisplayName parameter.
